At the Expo 2012 in Korea, Hyundai Motor Group staged a mind-blowing display using a controller area network (CAN) called mechatronic. This is a message-based protocol originally designed for automotive applications and now also used in areas such as industrial automation and medical equipment. Hyundai’s Hyper-Matrix installation was designed by Seoul media arts firm Jonpasang. In just two months, the team built a mammoth three-sided display out of thousands of Styrofoam blocks that could be manipulated like pixels.The 11-inch cubes were driven by 3,375 customized actuators and stepping motors that moved the blocks back and forth according to a specially prescribed program. The high-speed data transfer program constantly reconfigured the cubes to create a mesmerizing show.
