Solar Ping Pong Dot Matrix Display

Michael Zoellner of Erlangen, Germany, created this display out of solar-powered lights with ping-pong-ball diffusers.

The pixels of the 5×3 dot matrix type are arranged in two layers on a grid. Thus they are only readable from a position in front of them. Viewed from other position looks like random arranged light dots of a led chain.
