[Kim Pimmel] made nice light-painting stop-motion animations using an Arduino Bluetooth, Processing and some post-production.

The video is stop motion, so every frame is an individually shot photograph. Each photograph is a long exposure photo, with exposures reaching up to 20 seconds in some cases.

To control the lights, I used an Arduino controlled via bluetooth to drive a stepper motor. The stepper motor controls the movements of the lights remotely from Processing.
