The psychedelic colour cycling bicycle wheel part of the screen saver's display is an extended version of the wheel drawing code that I wrote for use in my spoke length calculator program's spoke pattern explorer. The numbers of spokes and spoke crossings and the hub size varies with some impossibly extreme values used to create some interesting patterns. The wheel colour cycles i.e. the spokes and background colours change as the animation runs. It creates some nice effects.In the example output below the sprites are the same as the animated cyclist in a yellow jersey shown in the top left corner of this page drawn in different sizes. They bounce around your computer screen and pedal a lot.
The example screen shot was done at 640 x 480 resolution. At the kind of higher resolutions that most people actually use these days it will look just the same but bigger. I resisted the temptation to show you a 1280 x 1024 example for bandwidth reasons.
As an alternative to the flying bicycle sprites you can have Flying Machinehead's
