"Autism is a neurological disorder characterized by impaired social interaction and communication, but often autistic individuals will posses amazing skills in other areas, such as music, memory, mathematic computation, etc. Artist Stephen Wiltshire is autistic and has an incredible memory and hand, as he was able to create a spellbinding 18-foot drawing of New York City from memory after only a 20-minute helicopter ride over the city."
