My brothers & sister in EMEA have been busy. They have launched an curious application called UniveRSS.
UniveRSS is a 3D RSS feed reader for Windows Vista. It leverages the Windows Presentation Foundation and provides a stunning way of visualizing RSS feeds and their content. It introduces a full-screen 3D universe where galaxies represent the folders of your RSS feed directory, and the stars are represented by the spinning cubes that hold the feed information. Size and position of the feed cubes indicate how many unread items they contain.
It installs as a click-once application, which is a nice touch.
Give it a try - it's quite an interesting way to look at your feed universe.
