Here is a cool screensaver so you can see twittervision tweets from your desktop screensaver. Here is the description from the release post:

"I've put up a new version of Visionary Saver the Twittervision/Flickrvision, and now Twittervision 3D and Twitter Flash RailsConf visualizers. The options panel is a bit different now - it's just checkboxes. If you want to randomize between different visions, just check which ones you'd like to randomize for."

The download was a .dmg for Mac.  We don't know if there is a windows version or not.
