This is so OLD. Like, 2001. Yeah, OLD. From Highschool (it was haield as very inventive though). But we were all given white scratch paper (the colorful paper stuff with white wax over it? That stuff! :D) and told todraw an image that could make the colors really come through. I believe, at the time, the teacher told me she couldn't have thought of a better subject (90% of the others were flowers and butterflies.)
