Memory power + drawing

I don't know why I didn't post this sooner but it came to mind since my trip to Japan. (don't worry...you'll see some of the pics soon) It's a video showing the artist, Stephen Wiltshire, drawing a 360º panoramic view of Tokyo..from memory! This is amongst the most impressive things I've ever seen done with a pen or brush. Yes, even more impressive than elephants painting or seeing HeavyWeight artists painting or that video by Blu.If you've seen aerial pictures of Tokyo or have seen how insane this challenge is you can start to realize how amazing this is...if not, just watch and you'll see what I'm talking about. Hint: most of the best artists in the world could not do this if the could see what they were drawing. Oh, and keep in mind this is with ink (no erasing).
