Uses for Leftover Crayons

For the past 10 years at the end of each school year I've collected crayons that my students no longer want. On my recent mission trip to India I took two, gallon-size plastic bags full of them for the children, but there are still a good deal left and the collection continues to grow. 

Melted Crayon Art

Every year I try to think of an art project to do with them. I have often melted and dripped them over bottles, or scraped them onto paper that I would then fold and iron. The other day while shopping at the teacher store, I found a new idea. It looks like it was done by melting one crayon after another in a pattern across a board, then hot gluing the same color crayon above each river of color. It might be a lot to do for one student, but I thought I could pair them up to work together. What kind of projects do you do with your leftover crayons at the end of the year?
