In no particular order, here are three of the cooler things I’ve seen at this year’s show:
1. Audi’s booth: I haven’t seen any pictures that do it justice (including mine), but it’s basically like standing inside of a light bulb.
2. The four Parrot AR.Drone quadricopters that perform synchronized “dance” shows.
3. Motion-sensing Legos that can be controlled with an iOS device to throw things at people.
