With the generous tutelage of my pataphysical colleagues Dr. Heatshrink, Dr. Geo, and Dr. Noname, I made this box of maple, alder, walnut controlled by an Arduino Feather connected to ultrasonic sensors, making it possible to change colors by waving a hand or walking toward or away from the box. To display the blocks I made for my grandson.
