Cool . . .

Check out this quick read. It's about how scientists are working to help the blind to see:

"The retinal implants communicate with an external camera and computer. The person who receives the implant has a pair of glasses which include a video camera. Visual data from the camera is processed by a computer, the processed data is then sent to the implant - all this is done wirelessly. The electrodes in the implant turn the data into electrical impulses which are sent into the brain, which in turn interprets the visual data."

Pretty cool.
