The NextFest expo in San Francisco last week delighted goers with air cars, invisibility digital-camo outfits, and a brainball game. NextFext had many cool robotic delights also such as the fact that robotic experts predict there will be a multi-billion-dollar robotics industry by 2006. Also, ASIOMO made an appearance. Extreme tech has a cool slideshow of what you could have seen there. SfGate.com has a cool picture of the Video T-Shirt movie trailer advertisement for the upcoming I,Robot.
