What does one do with over 1,000 LEDs, white acrylic, and 288 IR sensors? If you’re Redditor “jordy_essen,” you create an interactive light panel.

In one mode, the user pull a reflective tool across the sensors to draw a paths, with potentiometers implemented to select the color. It can also be set up to play a sort of whack-a-mole game, where one has to activate the sensor in the same area where it illuminates.

For this amazing device, jordy_essen uses not one, or even two, but six Arduino Mega boards to drive the LEDs directly — in turn controlled by a webpage running on a Raspberry Pi. If that wasn’t enough hardware, an Uno is tasked with taking inputs from the color potentiometers. 

It’s a brilliant project in any sense of the word!
