Mads Christensen designed and made What are You Blinking about, a light art installation first shown at Create:Fixate Los Angeles

Each of the three 40″x40″ panels contain 900 WS2812B LEDs driven by a Teensy 3. The Teensys stay in sync with each other using a serial connection. The red/blue light sequences are generated algorithmically at up to 100 frames per second, creating subtle moire and interference patterns on the viewer’s retinas due to the interplay between rods and cones in the human eye.
