I love photos and other photographers. I joined Flickr so I could host my photos and interact with other photographers. Through Scobelizer I learned about Flickrvision. This is a cool website from Dave Troy that is constantly updating with uploaded photos from Flickr users from all over the world. As a new image is posted the map shifts to the user location and the image appears. It is really sweet. I suggest that you make your screen full screen and use this as a screen saver, it is really pretty awesome and you can randomly see some cool photos from some great photographers.
