This is a wooden box that contains a matrix of leds. Thanks to an accelerometer, with some math and physics it’s possible to move the pixels on the matrix as real balls in a box that interact physically while you move the container.
The whole system is controlled with a Wemos board that allows also internet connection, used to change parameters and perform additional tasks (like displaying words).
