The Tech Museum
The Tech Museum in San Jose selected a few exhibits from Maker Faire for it's "Maker Faire @The Tech" exhibition that ran for about 3 months after Maker Faire
For this I made a dedicated balance board with it's own accelerometer, as well as a new hand controller. You switch between them by pressing a button on each. This wasn't the best arrangement because someone would be using the balance board and someone else would pick up the hand controller and press the button out of curiosity, and suddenly they'd be in control without knowing it.
Apparently the exhibition received 40,000 people and the maze was going continuously. The only problems it had were that the gimbal I'd made out of PVC pipe cracked a couple of times and had to be replaced, and one of the cords came away from the board and resulted in a burned out motor.
