wireframe and alien scooters

While you can't tell from the pictures, but the two scooters chase each other around the planet, each with a unique personality. One tends to lag behind the other one, but it will occasionally cut some corners and then get ahead, bragging (by blinking) to the other one. The first one periodically goads the follower by blinking as well. The "logic" is really just a bunch of perlin noise functions, transformations, and thresholds. The whole scooter thing is just an experiment in adding colored lighting to the scene out of control. When a scooter blinks, up to four extra point lights are stacked in the scene for extra brightness. I'm not sure how much time I've just spent watching them run around while I tuned the constants. I had to make camera controls for myself just so I could watch them.
