I appreciate the link, but as far as using it aa a screen saver, that's not what I'm looking for.

I would think if this mac After Dark project is open source, the assets would be available to use in other software.

I googled "web page as screensaver", saw results for Windows.

But I get the impression you want a ready-made solution for you, not do your own plumbing...

That would be great, of course. I have found a ready made Flying Toaster screensaver floating around and used that. But, I figured if someone had done it for Mac, surely there'd be a Windows version out there.
