Twingly Screensaver is an interesting visualisation of blogosphere activity. It renders a turning globe with blog activity spiking out from different parts of the world. It reminds me a bit of Mapped Up.
Traditional feed aggregators are still a lot more powerful for churning through news than this. But this kind of visualisation could be useful as an adjunct for trend watching. They should really allow you to keyword filter Twingly Screensaver.
(It requires Windows and OpenGL but works OK in Parallels.)
