This draws a bunch of moving circles which switch from visibility to
invisibility when they intersect.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific

Number of circles. Default: 32.
Number of colors, only one of which is used at a time.
How fast the color changes (0 - 100). Default: 10.
