OT: How Amazing

I saw a couple things about letting blind people see. One was shown in my engineering class, an engineer jacked into the optical sensors(I think) in his brain and hooked it up to almost a mini video digital camera. Supposedly he had very good sight from it, but wll not expand on the idea because he fears the radiation from his device will cause brain tumors. Another device shows the differenc in light with white and black dots, giving partial sight to the blind. They showed what the blind person would see with this device, and it looked decent at least. I think the latter was shown on ripley's believe it or not once
