Here's a Kickstarter project from the EyeWriter team — EyeWriter being a set of free/open libraries and hardware for doing eye-tracking for input and robotic control. EyeWriter has its inception with TEMPT1, a famous Los Angeles graffiti artist who was paralyzed by ALS (Lou Gehrig's disease) but who has been able to go on working thanks to the EyeWriter tools.
Now TEMPT1 and the EyeWriter folks are raising $15,000 to "create a new collection of original TEMPT1 artwork and merchandise using the EyeWriter 2.0 software, robotic technology, traditional print-making techniques, as well as his community of friends, fans and peers. Supporting this campaign will not only allow TEMPT1 to continue to make art and express his ideas, but it will give him a chance to again become a professional artist, independently support himself and his family, pay for his medical bills, and make a contribution to the contemporary art world."
TEMPT1 & EyeWriter = Art by Eyes
