In the late 70s as a ten year old, I spent a while drilling a spiral of holes into a12" vinyl album. I have no idea where the plans came from but the idea was to have one side the camera and the other side the output ie at 180 degrees. Did the drilling, got the meccano motor drive working got some light output but enthusiasm fizzled out about there.
