I had a chance to go to Wired's NextFest last weekend. The most interesting thing I saw was actually ahead of me in line for will-call tickets.
There is a lot of white scrim and video projections in the furture.
The most interesting stuff there was in robotics but it all sufffered from poor exhibiting and a lack of "theater".
This dance partner robot's design is quite surreal.
Saturn's use of video projections on cars was the best executed exhibit idea.
There was some very well done 2-d graphics. The standout for me were the graphic components of the Virgin Gallactic exhibit. The logo is dope.
