OH, Nelly! This is good stuff... If you are a Mac OS X user, have a love for great photography, and want to give yourself something to look at on that new 24" screen of yours... Check out the new public beta of FlickrFan

It's not a "double click, install" application, but with a few screens on your web browser you should be able to install and setup this very cool application. Basically a RSS reader for photos, it loads up folders on you Mac with pictures from RSS feeds of your choice, then using the built in photo screen saver on OS X to display the photos. Simple yes, super cool double yes!

PC folks are excluded at this time, but don't worry stuff like this will always trickle over.
