Stephen Wiltshire has an amazing ability to draw full city scapes from memory. Stephen was diagnosed with autism at age three. He has the amazing ability to memorize entire cities from one helicopter ride and then can draw a panoramic view of the city. He is also extremely accurate, down to the number of windows on a building. I thought this was amazing. Go check out his website and look at all of the cities he has drawn. There are also videos of him drawing the panoramic views. This is Amazing!
