The DVD screensaver was perfect: unobtrusive and did what it was supposed to do: prevent your CRT screen from burning-in an image. On top of that, it gave you something to look forward to when it would perfectly hit a corner (which some people thought was a myth; sadly the GIF version does not).
Now, any screen in your home is fair game for intrusive ads. Why make something simple, elegant, functional, and unobtrusive when that otherwise idle (or even in-use!) screen can be crammed with ads.
Dang. I see what you mean, lots of videos of the screensaver but not many gifs with the sweet spot of a corner. But I did find one that immediately puts out the goods
