I don't think you give the screensaver author sufficient credit for his
diligence in creating a quality product and trying to keep it up-to-date.

I think he may often feel compromised by intermediaries between himself and
users in the timely dissemination of material he keeps up-to-date. His angst
indicated in a pop-up is nominally directed at a distributor, but we all
know the user is also often at fault in keeping things up-to-date.

The screensaver is also an excellent test of computer video capabilities,
it might be added.
