Kinetic Light Installation
Addressable LED,  Arduino, Threads, Stepper Motor, Laser-Cut Acrylic


“Under Current” is a kinetic light sculpture built from two laser-cut acrylic rings, dozens of reflective threads, and a single slow-turning motor. The rings sit one above the other. When they twist at different speeds, the white and rainbow threads fold, fan out, and tighten into new geometric shapes, as if an unseen hand were pulling them. Addressable LEDs mounted inside each ring wash the threads with shifting colour, so every small movement of the motor shows up as ripple-like shadows on the floor and walls.

I wanted to stage a quiet conflict: order versus chaos. Half of the threads are plain white, half are brightly coloured; together they look like a tidy lattice until motion breaks that symmetry. As the motor turns, the lattice resembles a cage that is trying—and occasionally failing—to contain its own shadows. That tension between rigid framing and restless movement is the core feeling I hoped to share.
