Here's what I made with two of them. They are little winter
vignettes(scenes). The first one is a snowman ice fishing
and the second one is santa. The pictures aren't very good
but at least you get the idea. The first one is a snowman
ice fishing and the second one is santa.

These two sites have some more ideas.

You should go to the garden junk forum and search or just ask the same question, a lot of people there have made suncatchers with them, gluing 2 together with shiny side out and useing fishing line to hang them in the gardens or just from trees. some of them have drilled holes and attached wire and marbles......its really some neat ideas.
