BEARINGS GLOCKEN II is a robotic glockenspiel created by KAWASE Kohske. Check out the link for a lot more videos and pictures.

I paid particular attention to the following two points: First, I focused on the fact that “science and technology” and “artistic expression” have always developed hand in hand. Leonardo de Vinci, who invented principle of bearings, shows this clearly.
The other point is realizing “live sound” through performance. We have fewer and fewer chances to experience “live performance.” These days we can even listen to music on mobile phones. But, I want people to know the richness, power, impact, and vividness of “sound created right before your eyes.”
