Rain drops keep falling on my head.

The standard map is the first chaotic thing I remember seeing, probably in an AfterDark screen saver. It has an interesting physical interpretation involved rotors, but that isn't important for the pretty pictures.

$$ x_{n+1} = x_n + K \sin(y_n) \mod 2\pi $$

$$ y_{n+1} = y_n + x_n + K \sin(y_n) \mod 2\pi $$

Clifford Attractors are attributed to Clifford Pickover. They're reminiscent of smoke gently wafting in still air. paulbourke.net has some more images, and generates colour in a different way.

The formula has four parameters, each chosen randomly on $[-2,2]$. Not all random combinations generate a strange attractor. In some they fall into a fixed cycle or even a single fixed point. If that happens click the Restart button to get a new set of parameters.
