Description

This is a clock with a floating display based on Aerial Imaging by Retro-Reflection (AIRR). The numbers from individual LED panels are projected using a beamsplitter and a retroreflective foil. For the observer the numbers seem to float in the air a few centimeters in front of the clock's screen. To enhance the 3D impression I added servo motors to the LED panels so that they can be tilted. This makes the digits seemingly rotate in and out of plane.
