Andrew Hall builds custom LED light rigs that spin in patterns to make these lovely orbital light paintings. Andrew writes: 

Using a long exposure and various home built rigs, I photograph small colored LED’s as they spin on controlled axes. Repeated circular orbits overlap to give a three-dimensional appearance to the pattern, which can be further manipulated by altering the speed and direction of the spin.
