Ever seen Strange Days? Pretty amazing that they were able to do that, but, yeah, potentially disturbing as well.

I have to seriously question the "image converted from brainwaves" with Steve Martin from the article. The article says "n one scene featuring comic actor Steve Martin in a white shirt, the computer reproduced his white torso and rough shape, but was unable to handle details of his face." That seems a far cry from the digitally blurred image that they claim is the "image converted from brainwaves."
Thing works great. I just tried it out, I was told to visualize L2G's favorite thing to have for lunch. Flawless!
