I was doing an experiment with lighting for our Camera club and this was an easy way to illustrate Rainbow color effects using nothing more than a new DVD, placing a black cloth underneath as a background, water drops, bubble soap and a very small pocket flashlight. This only takes a darkened room on a table to achieve. This does require you to have a tripod and use time exposures to allow recording light as it travels across the surface of the DVD. When you run the flashlight beam across the surface you will notice the light beam being split into colors reflecting off the coating on the surface of the DVD. Raise and lowering the height of the flashlight will give you different colors and moving the flashlight around the perimeter of the DVD for 4+ seconds time will give you washes of color. This can create some very nice color screens to be used for screen savers or just a little fun in doing oddball types of photography you might want to share. I mixed it up a bit by using a rather large syringe to create different size drops of water on the surface of the DVD and then later used children's bubble soap to create blotches of liquid. The constant raising, lowering and rotation of the light and the material you add to the surface gives you tons of creative images. It becomes a little addictive as to what other twist you can bring to the setup. Be advised you will have to remove dust, lint and spots in your favorite photo editor to clean up your images.
