Zork and Tic-Tac-Toe on a LiveScribe Pen (YouTube) — this guy totally ported the Z-Machine so he can play Zork on his pen. My favourite bit is the comment from Infocom founder Scott Cutler: As the implementer who wrote the first Z-machine for the TRS-80 some 30 years ago and one of the founders of Infocom, I was thrilled and impressed to see what you did. I can guarantee you that we never imagined it would be played with a pen! (via Joe Johnston and Jason Scott)
