The cauldron is ringed with 8 piezo sensors that pick up every tap, knock, and stir as a live signal which can be mapped to anything, so a simple physical gesture becomes a way to control visuals, sound, spatial installations.
Hardware Stack:
Arduino UNO Q for sensors (piezo) and (psu-gyroscope) + Arduino Leonardo for L.E.D control.

Controller Interaction Demos:
The following demos are examples of how a digital artwork can be controlled by stick tapping or how spatial audio can be distributed by moving marbles along the rim or how a neural network can be glitched based on stirring the cauldron.
