I saw this really neat art exhibit at the Folk Art Museum in New York City the other day, called "Obsessive Drawing." It presented the works of four people who have spent countless hours -- years, really -- making drawings that have an obsessive quality about them, a need to fill space repetitively, trance-like.
It was kind of scary, yet compelling and wonderful. Sort of fits in with the "autism quotient" thread. You can get some idea by looking at these pictures. Check it out. If you're intrigued, read the New York Times review at the bottom of the page for more info about these remarkable pictures. http://www.folkartmu.../default.asp?id=1266
Reminds me of an interview I heard, many years ago, of a man who had sheds full of journals, floor to ceiling. He started recording his daily activities and got ever more detailed. Soon he was reporting on the number of steps he took to get to the refrigerator, the number of peas on his plate, the lint on his shirt, etc. He actually didn't have time to "do" anything because he was so busy recording every detail of what was happening and these activities interfered. Funnily enough, he seemed quite happy with his life.
