A rather sophisticated simulation of a bouncing ball in a box. This simulation is completely analog and has been performed on a historic Telefunken analog computer RA 742. The ball rebounces elastically from the bottom of the box as well as from the walls to the left and to the right. More background information about the simulation and the corresponding analog program can be found here: http://www.analogmuseum.org/english/examples/bouncing_ball/
