That was pretty amazing, haven't seen anything like that since your man in Oxford who worked out pi to 25,000 digits.

The guy, Arthur Benjamin, has book out called "The Secrets of Mental Magic"

http://www.amazon.com/Secrets-Mental-Math-Mathemagicians-Calculation/dp/0307338401

I seen it in Chapters in town on sunday btw...

I have the book & only did a little bit (got too busy with other things) but the book will teach you how to do this stuff, well I'd say half of his lecture he was pretty crazy :cool:
