A simple technique, where you hang a flashlight from the ceiling, and set up your camera on a tripod or flat on the floor beneath. Using a shutter release cable and shooting on Bulb Mode (so I could do an exposure longer than the pre-set of 30 seconds on other modes), you set the flashlight swinging, and hold the shutter open with the shutter release cable for about 60 seconds. The swinging light will record as a spirograph. Different light colors require different shutter speeds, so you have to experiment a bit.
