Massimo Banzi (flanked by Tom Igoe and Dave Mellis) gave this talk at World Maker Faire 2010 in New York. In case you couldn't be there, or in case you want to see it again, here it is.
Apologies for the less than stellar video and audio quality. I shot it with my Flip Video, which is ok, but not at all spectacular. I used a monopod, which is why it's not super jittery, but it means I had to stand in one place for 50 minutes. When the camera sways a bit from side to side, it's me shifting my weight because my feet hurt.
Too much information? Nonsense.
