I've been watching the TED videos recently, and there's some very interesting stuff (who knew Al Gore could be that funny?), but this one of Jeff Han displaying a new type of user interface is amazing. If you're interested in data visualization, check out the Hans Rosling one as well.

Excellent links Sandy ... the Hans Rosling one should be required viewing for all school children, and all politicians.
I agree, I've been carrying the Rosling one around on my iPod and showing it to everyone who will sit still long enough.
