zzHanoi Screensaver presents you with a rotating and shape swapping graphic.

At the start of the screensaver, there are three separate poles set in bases one of which has what appear to be tiered levels like a cake. As the graphic goes through its animation the tiers randomly swap out between the poles all the while rotating.

zzHanoi Screensaver comes in a zip file as a .scr, which is typical of most screensavers. To use it, just right-click on zzHanoi.scr after extracting from the zip file and select "Install" or "Test" to preview it before installing. The screensaver properties window will pop up to configure your settings however this particular screensaver has no additional settings
