I was always too poor to spend that much money on a screen saver like After Dark, let alone the Flying Toasters Pro plugin. We all know how important it is to professionals to have Flying Toasters Pro over the standard Flying Toasters.
After Dark. I remember the Star Trek module. That one was pretty entertaining. Especially the thing where Spock randomly wandered around your desktop taking "readings" off stuff and every now and then one of those magma monster things would crawl on screen and he's go mindmeld with it and scream "PAAAIINNN!!"
That was pretty much the height of computer technology in 1991 I guess.
It was crazy how popular this was. I have to assume it came with a lot of machines because I still have a legit copy on 5.25 somewhere and those were in the days before people realized software was something you had to pay for.
