Back in College I made this mobile/sculpture, I can't even remember what class it was for. I hung it in a front window of our house. The top structure is made of pipe and wire and the strings are a silver thread. The shiny pieces are bits of broken CD that I drilled through so I could string them onto the mobile.
When the sun hits just right it feels like you are in an aquarium. There are little sparkles everywhere in that room!
