Wisp, They tried using a bit map on a blind guy, and guess what: He could see in the same pattern that they were showing on the computer. The visual cortex sees images through brain signals in a grid like fashion. You can actually poke different parts of the brain with electricity and you will see it in different parts of your vision. By the way some people do think in words, my brother does. He has a very hard time visualizing things. I think in pictures and can rotate a 3d image in my head accurately.

So do us a favor, before you say something is impossible do some research so you don't sound like a moron to those that actually know the field of study.
