Autistic Artist Draws New York from Memory

An autistic artist who was able to draw an 18 ft picture of the New York skyline from a 20 minute plane ride on memory alone. This is incredible and I can't imagine being able to do something like this in a million years. The pictures above are an actual picture and his picture side by side so you can see he remembered the specific buildings.
This makes me think of how some of the best artists were a little insane in the membrane. Pretty much all of them had a mental disability. Be it depressed, schizophrenic or autistic. I have actually had this discussion severial times. It's like how if someone is blind their hearing gets stronger. Some of the most talented people fail in other aspects. Leonardo Da Vince only had 7 finished works by the end of his life. Edgar Allen Poe was an alcoholic. Vincent Van Gogh commited suicide. There is a fine line between genius and insanity. I find it interesting and I don't think it's true in every case. It is fun to think about though.
