Radar Profile: Saul Griffith, Maker Extraordinaire

Photo by Tim O'Reilly When I first met Saul Griffith in 2003, through a series of fortunate coincidences that brought him to our first Foo Camp, he said, "Our worlds don't really overlap." I represented the world of open source software and the web, the immaterial world of cyberspace; Saul, as he said in a 2004 interview for the Australian Broadcast Company, is "someone who keenly observes the world and then likes to tinker with it," a scientist, an inventor, a worker in the world of stuff.

Of course, as readers of Make magazine recognize, those two worlds are on a collision course, with "smart stuff" -- the infusion of computer-driven intelligence into objects and materials -- being one of the most important trends in technology. Saul is one of the pioneers in this new world, and since we met him, he has been one of the people who's done the most to shape our thinking about this coming revolution.

So it is with great pleasure that I share today's announcement that Saul was selected as a MacArthur Fellow, a recipient of one of the Foundation's so-called "genius grants."

The term "genius" makes Saul very uncomfortable, but he certainly fills the bill, a scientist and engineering polymath feverishly spinning out more big ideas than even he can possibly ever bring to fruition. He's also got enormous idealism. He's passionate about teaching kids how to be scientists. He wants to build things that will change the world for the better.

One of Saul's dear friends, Tim Anderson, has a better definition of Saul's "genius." In an account of some of their early experiments with new equipment for the young sport of kitesurfing, Tim wrote:

For a while it seemed like every kite excursion ended up with Saul in the emergency room.... Saul is the world's greatest optimist, which makes him very accident-prone. He has quite a collection of scars and an almost complete set of x-rays from breaking most of the bones in his body over the years.

The image says a lot about Saul: the world's greatest optimist, who is always getting in trouble...and then finding his way out of it, so that it's easier on the next person.

And indeed there is a connection between incurable optimism and risk-taking, between deep scientific investigation of the physical world and extreme sports. (It's only relatively recently that science became a matter only for the laboratory. If you think about the origins of science, you realize just how deeply it's tied up with exploration and risk.) Saul plunges into the world with the expectation that everything, and I mean everything, is malleable, that he can solve any engineering problem, and he has a willingness to put everything on the line to prove it.

Disclosure: Saul is a columnist for Make Magazine, and Howtoons, his brilliant series of science and engineering cartoons for kids, is featured in every issue of Make, and he has presented at numerous O'Reilly events, including Oscon, ETech, and the Maker Faire. Saul is also my future son-in-law. That almost kept me from writing about him here, but that's silly. I've long wanted to write a series of profiles of people who've profoundly shaped our radar and extended our thinking in new directions. And Saul is a great place to start, because he is virtually the archetype of a new breed of technology innovator who is at the intersection of computing and the physical world.


Smart Materials

Saul's Masters thesis at MIT was entitled Towards Personal Fabricators: Tabletop tools for micron and sub-micron scale functional rapid prototyping. [pdf] It took a "traditional" tools-based approach to the construction of new materials. But by four years later, he'd taken a different turn. His PhD work at MIT was on self-assembling systems and the design of programmable materials. As described in the abstract of his paper that appeared in Nature:

Autonomously self-replicating machines have long caught the imagination, but have yet to acquire the sophistication of biological systems, which assemble structures from disordered building blocks. Here we describe the autonomous self-replication of a reconfigurable string of parts from randomly positioned input components. Such components, if suitably miniaturized and mass-produced, could constitute self-fabricating systems whose assembly is brought about by the parts themselves.

The full article can be found here [pdf]. If you want to go deeper, take a look at Saul's PhD thesis, Growing Machines. Saul also described some of his work in a talk he gave at the TED conference in 2005:

The key idea that Saul began exploring was one of changing the relationship between tools and materials. We tend to think of materials as shaped by tools, but that isn't the only way to build things. Living things grow organically, with the instructions for their own construction somehow embedded in the materials themselves. What Saul showed was that even today we can construct primitive mechanical systems with the same characteristics. A set of parts with matching physical characteristics might randomly self-assemble into repeating strings, much like DNA, or fold into complex, predefined shapes, like proteins. Effectively, Saul was doing some of the groundbreaking work on programmable materials.

However, Saul's insight about new ways to make things doesn't just rely on new materials yet to be designed. A lens formed by the same physical laws that shape a waterdrop, a kite as an optimal energy surface for capturing the wind -- these are objects and manufacturing processes that can be revisioned by a better understanding of the laws of physics. As Saul told Wired, Squid Labs, the company that Saul co-founded with some fellow MIT graduates, is "a design firm that does differential equations."

Making the World a Better Place

Another of Saul's projects at MIT was a prototype of a machine for creating lenses, based on the observation that water drops "self-assemble" perfect lenses, an invention for which he won the prestigious Lemelson student prize. This low cost system for developing prescription eyeglasses for use in underdeveloped countries is a great example both of Saul's problem-solving technique and his idealism. Saul had worked briefly with a group distributing donated eyeglasses in South America, and found this to be an entirely inadequate solution to a widespread problem. These countries lack the infrastructure required for vision care -- using today's technology that means expensive diagnostic equipment as well as expensive molds for each lens type, and an inventory of lenses, leaving millions of people without corrective lenses.

Saul realized that programmable molding technologies could provide an entirely different solution to the problem, a device that could make custom lenses on the spot. (This would be an ideal technology to deploy as a microfinance business.) Not content to stop there, he realized that diagnosis was also a problem, and created a device to test vision using electronic sensors tracking the actual image produced in the wearer's eye rather than testing by an optometrist.

Science and Engineering are Fun

Also while at MIT, Saul began developing Howtoons, along with fellow MIT student Joost Bonsen and cartoonist Nick Dragotta. Each howtoon tells a story about science, engineering, and the process of invention. But cleverly, the cartoon itself also tells how to build the project.

Howtoons, the book, will be published by Harper Childrens next month. Click on the image below for details. howtoons book cover

Saul's sense that science has to begin with child's play goes back to his own upbringing. Born in 1974 to Ross Griffith, a professor of textile engineering at the University of New South Wales in Sydney, Australia, and Pamela Griffith, one of Australia's leading artists, Saul grew up in a rich environment of observation and hands-on exploration.

In the Australian Broadcast Company interview linked above, he was asked how long he's wanted to make things. He replied, "Since I was five or six, I guess, or probably younger. None of my Christmas presents ever made it past lunchtime without being taken apart."

Saul's column in Make issue 8 [pdf] was about hacking toys and games when he was a child. In it, he wrote:

Shooting my sister with a water pistol was fun, but the most distinctly proud moment I recall was a game I invented for myself when I was 8 that entertained me for hours. With water pistol in hand I’d shoot a squirt at the very top of a window. The stream would dribble down the window, typically dividing into two or three paths. I’d then shoot the bead of water at the head of each path, which would in turn create two or three more paths.

Quickly, exponentially, the number of paths would increase and I’d be frantically shooting at a fractal of water droplets, trying to score the most direct hits before the first drop dribbled to the bottom of the window. This was analog Asteroids, that fabulous Atari video game, only higher resolution and more compelling than its computer counterpart. I can still feel the sense of achievement of having invented a cool game that soon was played by my other friends.

That story captures a lot about Saul: studying the world, playing actively with it, and then sharing what he knows. Those who know Saul and his family will also recognize Saul and his sister Selena as the prototypes for Howtoons protagonists Tucker and Celine.

Saul's Howtoons birthday parties for the children of MIT professors are legendary. The kids would work together to build some cool device, like the air cannon used to blow out the candles on the cake in the video below. Then they get to play with it. (Saul still does frequent Howtoons workshops for kids at San Francisco's Zeum, as well as at Maker Faire.) Unlike many brilliant scientists, Saul is also a gifted, charismatic communicator, both in writing and in person. He has already inspired countless others to follow in his footsteps.

Like most Australians, Saul continues to play as hard as he works. An Australian's sport is as much a part of his identity as his occupation. Saul's sport is kitesurfing, a sport he has helped to shape. When he began kiting in 1998, he quickly began remaking the equipment he used, experimenting at first, he says, mostly by taking away things that didn't need to be there. He soon began building more sophisticated equipment, and helped his sister, an industrial designer in her own right, to launch a kitesurfing equipment company called MonkeyKites.

Serial Entrepreneur? How about Massively Parallel?

After graduating from MIT in 2004, Saul co-founded an inventors' think tank called Squid Labs with fellow MIT Media Lab alums Eric Wilhelm, Colin Bulthaup, and Dan Goldwater. Squid's "Smart Rope," a rope that can detect and report its own breaking strain, was selected as one of Time Magazine's Best Inventions of 2005. Smart rope also led to some whimsical demonstrations, including a giant tensegrity harp that the Squid team built for an exhibit at the Cooper-Hewitt Museum in New York. One amusing anecdote: one visitor from Thailand wrote to Saul asking for a copy of the harp to use in his elephant orchestra!

Squid has already spun out three independently-funded companies:

  • Potenco, which is building the innovative power-supply adopted by Nicholas Negroponte for the One Laptop per Child project. potenco power supply

  • Instructables.com, a revisioning of the thinkcycle.org project Saul started while at MIT. This site gathers user-generated instructions on everything from engineering to crafts. (Disclosure: Instructables is funded by O'Reilly AlphaTech Ventures.)

  • Makani Power, an alternative energy company that is still in "stealth mode."

The Squid family of companies are all together in their new headquarters -- the abandoned control tower of the old Alameda Naval Station. They look out over the cracked runways to the bay, and they see the future -- a future they can make happen. (They also have one of the most spectacular views of San Francisco that you can imagine!)

One of the things that is so impressive about Squid and its spinout companies is the talent they've been able to assemble: the brilliant colleagues each tackling important ideas, the young engineers and interns with whom they are sharing their ideas and work ethic, visiting scientists and engineers. It really is quite remarkable, and on its way to becoming more so.

The Future of Manufacturing

Saul is constantly sketching, tinkering, thinking about how to improve everything he touches. Materials science, computational geometry, and natural history are all grist for the mill. Part of his strength is that he's a Renaissance man in an era where familiarity with computers meets familiarity with machine tools. Rebuilding automobile engines with makeshift parts (as he did as a teenager and as a traveler in Africa in his early 20's) is as much a part of his repertoire as computer science. He sees the physical world and the tools we use to interact with it as "hackable", so whatever he pursues, he pursues in a way that reinvents it, or, as the poet Wallace Stevens said, "searches the possible for its possibleness."

The workshop at Squid Labs is a window into a world that will soon be available to the rest of us. Saul and his Squid Labs colleagues can, in the words of MIT professor Neil Gershenfeld, "make (almost) anything". They have assembled state of the art equipment for rapid prototyping as well as a more traditional machine shop. Much as a programmer assumes the malleability of bits, the unlimited potential of the computer to reshape itself to the maker's vision, this new generation of hacker assumes that the world itself is malleable, and if Saul's thesis work is correct, ultimately programmable.

I have built my business "watching the alpha geeks". These are the people who are comfortable enough with technology that they aren't constrained by the intentions of the original designers of tools or devices, people who can push the envelope, demonstrating what's possible and paving the way for commercial inventions to follow. These alpha geeks (or "lead users", as Eric von Hippel likes to refer to them) are a great source of innovation from the edges, as they typically solve problems in markets that are under-served by traditional commercially-oriented innovators.

The kind of work Saul is doing is the front edge of a wave of innovation that is going to completely transform our society, as the potential of small-scale computerized manufacturing leads to new industries. Just as Napster and its sequels have challenged the business models for music distribution, personal fabrication will completely change the dynamics of manufacturing, distribution and sale of physical goods.

I have seen the future, and it's in Alameda.

Our parental pride in Saul's award of a MacArthur Fellowship is greatly enhanced by the generous, lucid and detailed account you have given. May I be permitted to add just one thought - Saul, by his achievements, has demonstrated that he is not slavishly an Australian, nor indeed American. He is a citizen of the world, a true Global Explorer, and here across the Pacific we are extremely proud of that.

While Saul's undoubtedly a genius, I'm proud to say that I knew him back when he was a smelly bare-foot kite surfer.

Oh wait, he's still ...

Anyway, in the proud tradition of Russell Crowe, pavlova, and Phar Lap, I claim Saul Griffith for New Zealand. I'd plant a flag in him, but the ANZAC Code has a clause against homoerotic imagery. Admittedly there's much less justification for claiming him as a Kiwi, given he was born and bred in Australia, but it's worth a crack. Tell you what, Australia: you can have Russell Crowe back—no questions asked—for a 50% interest in Saul. Deal?

In all seriousness, he deserves it. I've been in awe of him since I met him. Congrats, Saul! Party at your place, right? $500k should buy a lot of EL wire and schooners ...

Good Work Fella.

I've had the pleasure of studying with him at the Media Lab and there is no way you can keep up with his stream of activity. Truly a nice guy and I can see him hating the term genius, but he is one of our best multi disciplinary brains and one of the nicest guys i know.

I am so *glad* i turned down the offer of going kite surfing in New England with him in the freezing bloody cold a few years ago. :-) I am also glad he doesn't wear that almost trademark orange boilersuit anymore.

Saul: Keep pushing and tinkering mate, I'm right behind you with the ambulance and video camera.

All the best mate.

Surj.

Nice job, Tim. And congrats to Saul, though I am sure this is probably only one of many such honors and prestigious awards that will come his way!Having just come from a hunter safety class, it is obvious that the hunter/gatherer world we occupy out here is far away from Alameda, but it is electrifying to hear about all that you are doing/building/creating/imagining! Blessings Maggie

It's an amazing accomplishment in a long string of amazing accomplishments -- past, present and future, I dare say.


My fondness for Saul’s work lies in his passion for teaching kids to be scientists. In my experience (as the mother of 2 young boys and an editor at MAKE), today’s kids need to be taught that it’s OK to experiment, it’s OK to make mistakes in those experiments, and it’s OK to face a bit of risk, whether it’s in sports, in the classroom, or out in the forest building a fort.


After my 9-year-old met Saul, he spent the next few weeks enthusiastically coming up with ideas and inventions. The drill became a motor for his skateboard, an afternoon was spent with friends making elaborate marshmallow shooters, and a cheap video camera was duct-taped to the top of a remote control vehicle. Not all of these things worked, but 3 years later he’s building cars out of old fan motors and skate wheels, taking apart RC cars, and building forts in the forest with his younger brother. And he can’t wait for the Howtoons book to come out.


Congratulations, Saul!

Well, from a sibling perspective THIS IS FANTASTIC NEWS and it goes to show that the scribbling sibling, mechano maniac, leggo loving, plasticine pushing, dick smith kit doing, book burrowing, eager experimenter, sports spieling nine year old within is valued and indeed valuable.

We are all excited for you Saul and enjoy hearing of all your endeavors. It is brilliant that your creativity is being acknowledged.

lots of love

Terrific overview. I would like to add another Squid Labs spin-out to your list. This, too, is built on inventions Saul spearheaded or devised. I am Saul's co-founder.


OptiOpia (www.OptiOpia.com) is building the lens molder described in the article and also a low-cost auto-refractor, key ideas for which are Saul's. An auto-refractor is a device that diagnoses refractive error and enables the less trained (a) to screen people rapidly for the need for glasses and (b) to obtain accurate prescriptions to be used as an input to the lens molder. Together, a small gadget for getting right prescription and another compact gadget to make the lenses will help make it possible to have an optician's shop on the back of a micro-entrepreneur's motorcyle or as a kiosk-ish part of a general store or clinic in a small town or neighborhood.


Also, quite a bit more can be said about programmable materials. Thinking about the "computation of the shape of a raindrop" helps one recognize the manifold ways in which natural processes can be thought to "compute" a surface, a shape, a material property, a system's stability and dynamics, and how design and computation are sometimes simpler in analog mode with some materials than in digital mode.

Congratulations, Saul!

  Tim O'Reilly [09.27.07 01:13 PM]

Sorry, David. I didn't realize the lens molding project had actually been spun out as a separate company. I thought it was still a project within Squid. Congratulations. And thanks for the additional detail on the project.

  Siri Dhyan Singh [09.27.07 02:37 PM]

Hi Tim,

congrats on a fine addition to your family. I'm inspired just reading about him. I check in on your radar posts daily. Your visionary thinking and aggregation of great technology as well as business principles is truly a rich treasure trove. I feel privileged to have your wisdom and intelligence at work filtering for great content and ideas.

I would like to ground this piece out a bit though - especially this quote " . . . wave of innovation that is going to completely transform our society." From my perspective the major block in the damn for our societal development is our inability to transcend the basic animal impulse of a dominance hierarchy - there are individuals who have done it but no critical mass has been achieved.

On a continuum of inclusion from:


inclusiveness increasing ---->

self - family - tribal - national - world - universal

The idea that programmable matter is going to usurp that development I don't think adds up. A person at a tribal centric level of consciousness will just use that to build things to reinforce their tribal values to gain advantage over other tribes. The same dance will continue, perhaps at a new venue with some new steps added . . . but essentially the same dance.

The documentary "Born Rich" provides very strong evidence that even with nearly all material constraints lifted the societal dance and increasing ones circle of compassion is still a process that we all mature through.

Kind regards,

-Siri Dhyan
