Save all those little pieces and bits of crayon (if you have kids, I know you have a box of these laying around). Then convert them into funky little crayons!
You can also add a little bit of glitter before you add the crayon pieces to make sparkly crayons. Or stick to the same color family in each mold so you have a crayon in shades of red, another in shades of purple, and another in shades of green! So fun. You can see some of these ideas here.
