The Ars Electronica in Austria is a digital art laboratory committed to future art and technology. They tried multi types of multi area art research and turned the whole center into a huge Rubik’s Cube. They can transfer the changing data on the cube to computer through Bluetooth technology. Tourists passing by can experience playing cube on a building body screen. Ars Electronica Festival has now become an annual event of international digital art and attracts millions of tourists to visit every year. The application of led high bay is also getting famous. Those novel applications have accelerated the popularization of LED lighting; we are looking forward for LED Lights to turn from high-end to common.
