First of all, this will only work well at night but twilight isn't too bad either. What is required is a large wire burley cage as they use in fishing, a lightweight dog chain about 2 1/2 feet long and some steel wool and obviously something to light it with. I suggest a little lighter fluid and a match/cigarette lighter. Those taking the shots will need a camera (DSLR preferred) UWA or wide angle lens but you can get away with a standard lens at a pinch, a tripod and a cable switch. Mount your camera to the tripod and connect the cable switch, set the camera to "Bulb" to give yourself extended shutter open time.
With the Burley cage you stuff it full with steel wool, attach the chain to it then light the steel wool using a little lighter fluid and the match. Start swinging the cage in an arc and as the wind catches the burning steel wool it sparks with very bright light. The cameras should quickly focus on that light and cable switches held down until the steel wool burns out. This may take up to 30 seconds to happen. I'll add the exif data so you know what settings to use on your camera.
