Autistic Savants

The line between extreme mental capability and extreme handicap is a very thin one. I recommend this documentary "Brainman" featuring particularly Daniel Tammet who is lucky enough to be both extremely capable in memory and calculation while remaining relatively well adjusted to society and able to communicate his thought processes normally. The documentary features the real Rainman as well as Cambridge Prof. Simon Baron-Cohen, a renowned authority on autism and second cousin to legendary comedian Sacha Baron-Cohen.
