For some time, in a company where I worked, I used to have a screensaver called Mandala Screensaver. It was really colorful and good (IMO). Colleagues used to ask me for it. Just did a search for "mandala screensaver" and got some results which look like it. Use caution if downloading from any site, though, and scan with anti-virus, etc. After Dark was great too. Earlier, Windows' MSDN docs used to have sample code for a screensaver (in C, I think), which could you adapt, and just change the graphics to your own. IIRC I tried it out some and made a simple one or two of my own. Good fun, and could be used for things like task reminders too.
