Well, those guys are already bungee jumping! They walk around until you click on them, and then they jump. Right now the length of the rope is the same for everyone, but that's the next step.

Today I had to fight with pyglet to scratchs fps. On my first tests, the fps count dropped below 30 with just five guys jumping and ten or more walking around. However, thanks to batch drawing and vertex_list(s) more than thirty gys can jump at the same time while a bunch of them walk around waiting for fun! :D
