There was a time, many eons ago, when screensavers were a big deal, and the king of the screensaver makers was Berkeley Systems, creators of the famous "Flying Toasters" screensavers.
Bryan Bruan used CSS to recreate a lot of the After Dark screensavers, including :
- Flying Toasters
- Hard Rain
- Bouncing Ball
- Messages 2
- Fade Out
Why aren't screensavers that popular now? Like ringtones, people got bored with them, for one thing. But I also think people are using their computers for more hours in a day than they were in the 1990s, so there's not enough idle time for a screensaver to kick in.
