Here are two amazing TED Talks from Tan Le, John Delaney and Jeb Corliss. Le heads up Emotiv Systems, which is bridging the gap between computers and humans and how we might one day interact with them. Delaney is building a network of HD camera rigs deep under water. Corliss addresses fear and how to overcome it. You can check out Jeb’s death defying shenanigans, which he captures with multiple GoPro HD Hero cameras, here at his YouTube page.
