Lid of Vicky's box

My sister went to art college to study as a silversmith. One of her first projects was making a cylindrical box out of copper, with a perspex lid. The brass screws were then put in an the molten copper applied. I've always loved this box, but I don't really notice it anymore because I've had it for years. Well tonight I had fun with it out in the garden! Taking pictures of it on different surfaces.
It also reminds me of a programme i used to watch as a kid, when they showed you a small corner of a picture and you had to guess what it was!
