Well this example wouldn't necessarily need all aspects... just try a still image with a modeller and a texturer/lighter/renderer.

Challenge: Create a character in an environment on the topic of heros or villains. The modeller models the character and hands it off to the texturer while they model the environment. The lighter textures and lights the environment while the modeller offers support from the sidelines. I dunno, just get something going.
Duration, two weeks?
