I actually did this for an assignment for my photography class. We were learning about light and it's directions. But I think it fits this assignment well. I hope. Just in case you can't figure it out...it's an egg. the other elements: bubble wrap, a green nalgene bottle, a box top, a flash light (the only light source), and lime green tissue paper. I wasn't sure which one fit best so I am showing both. One is full silhouette and one has a light source partially directed at. The first may be more contre-jour.
