Livescribe's pen certainly seems like a hackable enough device, but for some reason we haven't seen many hacks or mods that make the smart pen even smarter (or dumber, for that matter). One big one quietly popped up last month, however, and has apparently gone largely unnoticed until now. YouTube user "chipos81" has managed to port Infocom's Z-Machine virtual machine to the pen (the Echo, specifically), and you know what that means: Zork on paper. Look down. Examine link. Go past break. Watch video.
