Interesting link. I have an older relative with Asperger's syndrome who is a complete frickin' genius at three dimensional thinking. He supported his family for years by selling specialized machine parts for flowing and binding fabric through industrial sewing machines. The guy is completely self taught. He's also pretty good at measuring to the millimetre by eyesight, identifying screw threads at a glance etc.
