Helping the blind see

As far as cool and useful products go, this seeing machine has to rank right up there with some really cool stuff like the cochlear implant and some other stuff that I can't remember now. I actually remember blogging about this ages ago but the blogger search engine can't find my post. Probably because I ended waffling on about aliens from a far away planet or something. 'Man, those aliens are really cool, did you see their spacecraft it was like some kind of flying saucer or something. Plus they looked like monkeys' Was probably how my post went.
