You will need: Water-based paint, a cake pan (with high edges), thick paper, tape, and marbles (or other weighted round objects, but weight is important!)
Tape the paper to the base of the pan. Add paint to the edges of the pan and paper.
Place the marbles in the pan and let your child roll them around. The marbles leave these amazing lines and it looks really cool. Queue my failure! I didn't have marbles on hand, but being the ever creative mom (or too lazy to run to the dollar store mom) I decided to use beads. The beads rolled until they got stuck in the globs of paint. Sadly, you need marbles for weight. So we abandoned the idea and my little princess used her fingers. I have feeling we will be trying this again after I track down some marbles, but the picture still earned a place of honor on the fridge if for nothing less than to remind me that my little girl is an amazing finger painter and there can be beauty in failure. Talk about taking some of the pressure off!
