Racing A Coffee Cup Vs. A Musical Keyboard?

Thanks to the Grandtextauto site for their post showcasing an exhibition using unique game controllers at the Japanese National Museum of Emerging Science and Innovation. The photos on the page show racing game controllers as wacky as a "..direct-manipulation coffee cup - the text on it reads 'Drink me. Drive me'", and "a synthesizer keyboard that moves forward when you play notes toward the center and turns when you play notes at the edges", as well as a horse you control with physical reins, and a more conventional steering wheel controller, all networked together and racing through a 3D model of the museum.
