Some UV LED flashlights, some bodging with a cordless drill + a plywood offcut + copper wire, and a compact camera with a "starry night" setting (long exposure, e.g. 15-60 seconds) allow you to create awesome light paintings very easily. It's essentially the ultraviolet, power tool version of the E bola. Stand still to create a circle. Slowly rotate to create a sphere. Walk around to create a wormhole-like tunnel. Walk away from the camera to create a hyperspace effect. It works just as well with other color flashlights too, of course - it's good fun, and you'll baffle people if you make one of these pictures...
See the second-to-last photo to find out how I put the spinning light source together. The spheres here are about seven feet across, and hover about six inches above the ground.
