For a while I used to run the Helios screensaver as a wallpaper on my desktop:<p><a href="http:&#x2F;&#x2F;www.reallyslick.com&#x2F;screensavers&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.reallyslick.com&#x2F;screensavers&#x2F;</a><p>It runs quite happily on the root window on a multimonitor setup. But I eventually turned it off after deciding that I never saw my wallpaper much anyway, and having flickering things in the corner of the monitor was making me twitchy.
