ROBOTANK This is a very nice screen saver, BUT it uses Flash and thereby an absurd amount of system resources. I would bring my comp out of screen saver or display sleep and notice that the Flash process had been running up to around 50% CPU. This is a bit much for a screen saver. To the previous poster: To uninstall this, all you have to do is remove the screen saver file from ~/Library/Screen Savers or /Library/Screen Savers (I can't remember which spot it puts it in). There are also a preference file and Flash rule created. You can just search your hard drive to find these files, though there's no harm in leaving them behind.
