blnk: Solar Ping Pong Ball Dot Matrix Display

The right perspective is necessary to read the message. Blink, don’t blink.

My latest experiment with dot matrix light installations. It’s much simpler than Shadow Meadow and Fireflies. I am working with only two layers of dots instead of a random number of layers. Thus i don’t need to calculate reverse 3D projection.

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.

Thanks to the solar led chain blnk can be placed anywhere. It charges by day and glows by night.
