Tony Quan a.k.a. Tempt One (graffiti writer, publisher, and activist) was diagnosed with ALS (Lou Gehrigs disease) in 2003, and is now almost completely paralyzed, despite having full mental faculties. Enter the Not Impossible Foundation and their new Eyewriter project. They programmed custom, open-source freeware that can track eye movements, allowing Quan and others to write and even draw using only an eye, a computer, free software, and about $50 in parts (including a modified PlayStation Eye).
