The popularity of animated Graphic Interchange Format has steadily decreased as modern bandwidth has blossomed. Nowadays we hardly blink when viewing 720P HD content online. Back in the day though, a succession of simple images used to be packed into a single file. It helped to create a visual very much like an old flip-card movie. Once, standard gifs were nearly as common as jpgs as a file format for image storage. I can even remember using the vector clip art that came with WordPerfect's WPG extention in the 1980's. This comes from a guy who once learned ANSI and RIPscript for BBSing before HTML won over the Internet. (Wow, that last statement should give me some old-skool nerd cred.)
Anyway, I caught a glimpse of this looped, animated GIF and decided that it must have once been popular. I grabbed a copy through a search. The resulting movie looks jerky as that's how GIFs were. Yet, I've blown this one up at least three times its orginal size which doesn't help with the clarity.
This is just my fond tribute to old PCs now in landfills polluting the environment in third world dumps: You sucked but we didn't know any better at the time.
