As I stated in a very old post:
Back when I was a young artiste, I used to fantasize about a computerized "Art Machine." It could manipulate shapes and colors, lines and textures, and make anything you wanted. Of course, it was big enough to fill a room, and in my fantasy I had a staff to make it work, because I really didn't know anything about computers. Oh, and to get the image perfectly from your brain to the screen, the machine hooked right up to your brain.
Fast forward to the present. I finally have my art machine, and it does just about everything I imagined back in the 70's. It's small enough to sit on my kitchen desk, between my coupon holder and the dog's medicine. Unfortunately, it doesn't plug directly into my brain, and learning how to make all the art stuff work the way I want it to is frustrating...
OK, so that was over 6 years ago. I have learned it little bit more about digital art and image manipulation since then. And I have just learned that the final, elusive, seemingly impossible component to digital art, that of extracting images directly from the brain, is becoming... a reality!
