I have used zap! pow! bam! by Colie's Corner. It is an awesome super hero kit. I printed out the elements nice and big and used them for a bulletin board at school. I had the kids write comics and put them up on this comical writing board. It is not quite finished, but you get the idea.
You can find this super kit here...
