Maybe I’m just not paying attention to the right arenas, but it seems like the “real-time screensaver” is becoming rapidly more popular.
You can get Digg and Twitter as screensavers, and I wrote about Twingly a month ago.
While I don’t use a screensaver (my monitor turns off after an hour’s inactivity), if I did, Newsbreaker would be it.
It appeals to me with all the geekiness of a game of pong combined with my info addiction: you can track up to 14 RSS feeds.
It’s also offered as a game. Woohoo!
