I've never read any of his books or anything but he was interviewed on the Screen Savers on Tech TV several times and it always made the show interesting whenever he was on.
I <3 him. He was at the Science Museum in Boston once during a field trip. I didn't get to see him though .
omgawd!!! I so want to lick his ears in hope of extracting just a tiny bit of his awesum smartyness!!!!
