I've seen this "thing" online of melting crayons over canvas to make art. I remember being a kid and our art teacher had this crazy molten crayon painting device. This isn't quite that technical, just line up and hot glue crayons, and use a hair dryer (or preferably a heat gun) to melt crayons to create motion. I decided to give it a shot. If I could do it again, I would definitely use a heat gun. To get a hair dryer to correct temperature you have to have it on high anf it just blows the stuff everywhere.
