There's a jillion apps like this. The one that seems safest and most reliable is Visage... even my G4/466 with a PCI 7000 can run low-impact savers like Dividing Space or Subversion (which is just too cool over a desktop picture) without bogging down using Visage. Go ahead, pay the man his shareware fee, it's a good hack. [no, I'm not the developer, don't even know the guy, I'm just a fella who had to boot to single-user to fix his file system after another screen-saver-on-desktop hack locked him up] Another nifty screen-saver tweaker is Saverlab.

Very cool Idea! Perhaps not fully cooked enough yet? All commands in the menu bar refuse to operate ,while this program is running, and all other apps slow down dramatically. Me thinks it's a memory hog, but I'm only running a G$ 867 with 1.5 gigs of ram.
