M.E. and I *literally* just finished doing shadow puppets. I sat behind our curtain and made the puppets and she watched and guessed what animals I was making. When we were done (because we went through the list I knew twice) she said, "gosh mom, that was big fun."
If you need some shadow puppet ideas (because you are like me and only know how to make a dog, butterfly, and bunny) click here.
If you want to feel like your skills are completely inferior, watch this--it's pretty amazing!
