Joshua Krosenbrink works for Usabilla and he has presented them with the World of Light, a map of the world represented by 426 RGB LEDs. The Raspberry Pi runs an API that is used to send data to affect the map and he has hooked up his company’s website so that when feedback is received, the map changes accordingly. A 30-amp power supply completes the picture. More photos are available over at Hackaday and you can see it in action below.
