Ohh! Ohh! I have dibs on the Nakoma Narrows bridge! And let's see,
towers in high winds, windsocks, parachutes, giant cartoon balloons, jet
exhaust cones, smoke and fuzzy dice in the cockpit! This is gonna be
fun. I wonder what the performance hist will be. I assume that it will
go linearly with the number of vertecies.
