Can't Start His Wank
MOBIUS STRIPS!
The low budget approach I see.
Make an exploding model BP oil rig. Besides being awesome and hilarious it would show, on a small scale, the effects of the disaster. Maybe have a bag filled with oil (maybe baby oil since it's not very flammable or some other oil-like substance) with a straw acting as the pipe that got cut off and have it sitting under sand in an aquarium.
And a big pile of money representing the profit from the rise in oil prices.
