A groovy little light diffuser consisting of three concentric rings that were once white but now have a hearty rusty patina to them. There are three little slots for bead-chains to hold it below the light. It came to us from a middle school, and it looks like it may have been an exterior fixture. A little bit of elbow grease and some oil-based paint and you could get this bad boy looking good, groovy, and shagadelic again.
