MSN Screensaver is now available for free by clicking here - the software is a beta version.
I like the screensaver as it includes an RSS aggregator that lists a summary of the latest posts (of blogs you've expressed an interest in). It also links into MSN Spaces - this is used as the source of the background images - very cool.
The screensaver also adds tabbed browsing, lists headlines from the MSN website (if you choose) and can display a local weather forcast for those who live in the USA. There's MSN Messenger integration too.
The new screensaver requires MSN Desktop search to be installed.
Below is a screenshot showing the configuration options.
