This post is also on a TV program. This was on a guy, Daniel Tammet, who is autistic on the positive side of the spectrum and possess exceptional mathematical and remembering abilities. For example, he studied 22,500 decimal places of the mathematical value of Pi and recited it to an audience. It took him 5 hours and 10 minutes to complete. As a test, he was monitored learning the most difficult language in the world, Icelandic, and he succeeded in giving an interview at the end of the week in the language. Amazing and yet awful in a way.

Rain Man, the movie, was inspired by one of the savants like Tammet and features Dustin Hoffman and Tom Cruise. I am planning to have a look at it.
