Roger. I got the idea from a light painting video on YouTube.
I cut out a circular piece of 1/2" blue board, bore a hole in the center and put a dowel through it. I then taped a battery operated string of lights to the outside. I put it on the floor and spun/pushed it around for several revolutions (this part took me several tries before I could get it right). I took the photo in my cellar, lights out, camera on a tripod, manual focused on the center dowel, and used about a 6-10 sec exposure. The 36" light string I got from the Christmas Tree Shop.
