Situation: where I work, I have an old (PIII 500Mhz, 128Mb RAM, no hard drive) computer and CRT.
Plan: create a welcome display screensaver
Implement:
-download Damn small Linux
http://damnsmalllinux.org/download.html
-dpms was turned off already (not supported by hardware), but if it had been,
$ xset -dpms
-turn off the "blank" screensaver
$ xset s off
-download pictures from the intrawebs
