"Mathemagics": Arthur Benjamin on TED.com
In a lively performance, “mathemagician” Arthur Benjamin races a team of calculators to figure out 3-digit squares in his head, performs a massive mental calculation, and guesses a few birth days. How does he do it? He’ll be happy to tell you. (Recorded February 2005 in Monterey, California. Duration: 15:14.)

This video of Arthur Benjamin working his mathemagic was a HUGE hit with my math-entranced six year old. Great family viewing.
