This is just a quick random animation with four balls leaving four different colorod pen trails and being attracted to eachother in the following ways. The red ball gravitates towards the green ball, the green ball gravitates towards the yellow ball, the yellow ball goes towards both and the orange ball is attracted to the red ball. Unfortunately the gravity is a bit wacky as the balls go faster the farther away the are from the're target's because the orbiters use the distance to the're target's to determine speed. Feel free to remix and add something to this as it is just a basic experiment and it feels like it could be turned into a game, use a spaceship to destroy all balls perhaps...
