Clever animated frames from Sprixels. We have seen a similar method used to replicate Nixie tube displays. More from Tom’s Hardware:
The artwork features slides of laser cut acrylic, each of which is illuminated by LEDs. As a sheet is illuminated, the image which has been etched on the acrylic is illuminated. By using multiple slides, and multiple light sources an animation effect akin to Neon signage is produced. The Pico is responsible for alternating between these sheets and controlling what colors appear from the LEDs. Sprixels has managed to daisy chain seven signs together using just one Pico as a controller.
