Back in 1993 two Finnish demoscene coders by the names of Dweezil and Tsunami came up (probably independently?) with a graphical effect that became known as the infinite fractal zoomer. Sometims it’s also called the Dweezil zoomer. The Linux xscreensaver knows it by the name of Kumppa. It is a clever and simple algorithm which allows even pretty slow machines to do an impressive infinite rotating zoom. Today I will talk you through the algorithm and we will do the actual implementation in Turbo C, using VGA 320×200 and 256 colors.
