What kind of crayon molds would you like to see?

I like the idea of making a crayon mold with my MakerBot.  I even have a draft design sitting on my hard drive.  However, what’s a good shape for a crayon mold?  Triangular crayons, square crayons, fat crayons, thin crayons, flat crayons, smiley face crayons, Christmas crayons, Halloween crayons, Valentine’s Day crayons, Easter egg crayons…

If you could have any1 shape crayon, what shape would you choose?
