Make animated swirly patterns which change shape. You can use real materials such as gold, pearl, ruby. Many demo patterns included for the screen saver (over a hundred) and you can make new ones to add to it.

Many pattern transforming effects included too, some related to things that happen with real world Lissajous patterns, or mathematical transformations of them - pattern drift so they continually change shape, gravity, magnet, inversion (turn inside out), transparency, friction, etc.
