Arc Attack's tesla coils
Among the projects on display was Arc Attack, an Austin group that has rigged tesla coils to a DJ system, making it possible for the electricity shooting out of the tesla coil to be timed to the beats of the music.

Rubik's Cube robot
The machine, built by high school students, relies on sensors that can distinguish between the colors of the individual sections of the cube. This individual device was not able to solve the cube, because of problems with the sensor that made it difficult to distinguish between similar colors, but it was representative of a device that can finish the task.
