About the simulations

The simulations are small experiments you set up and then watch. Some explore physics and geometry, such as Circle Illusion, where straight-line motion appears to form a rolling circle. Others play with colour and music, such as Chain Reaction, where every collision creates a new mixed-colour ball, and Growing Ball, where every bounce plays the next note of a classical melody.

Most have few or no controls, so they are easy to enjoy in a minute or two. Each page explains what is happening on screen and what to look for.
