Simulated Glowy Physics!
These LEDs interact with motion and looks like they’re affect by gravity. An Adafruit LED matrix displays the LEDs as little grains of sand which are driven by sampling an accelerometer with an Adafruit Feather.

The code, written by Phillip Burgess, simulates physics by calculating collisions and terminal velocity.

We designed 3d printed enclosures to take advantage of sensor readings by allowing it teeter totter as well as a gimbal to create interesting simulations.”
