I discovered TEDtalks on ted.com.
They have a wonder number of very interesting people presenting on varied technology subjects.
I sat back at home and watched presentations by Burt Rutan and Jeff Han, but there are folks like Jim Wales and Dick Dawkins and Steven Levitt there too.
The Jeff Han presentation was very cool. He was demonstrating some amazing touch screen interface advancements. Basically an interface without and interface.
Anyway this is very cool stuff, go check it out.
