ToPong is a pong for one player, which lives on a
Torus (=doughnut) in 3D space. The movement of the ball is along
geodesics on that torus. Geodesics are locally shortest or straightest
connections of two points. There is a flat version next to the 3D version
in order to get a better understanding for the mathematical content.
(We were thinking of extending ToPong to higher mathematical genii).
ToPong can be played online via a
Java-Webstart application. The two torus versions are displayed in
two different windows. Please wait until both windows are loaded.
The torus (=doughnut) can be rotated with the
right mouse button. The paddle on the torus can be moved by
dragging with the left mouse button. The speed of ToPong depends
on the abilities of your computer. It may be too slow on older
