Rainbow of Raspberry
summary
A wearable rig of colored lights maps hand motion to color and position, using Leap Motion for 3D tracking, a Java server on a Raspberry Pi exposing REST calls, and an Arduino to convert commands into voltages for the LED array. The system is built at the hackathon in about one hour, updates in real time as hands move, and demonstrates a complete end‑to‑end pipeline from gesture to visible rainbow across the body.
