Flappr is a Flash 8 interface for Flickr. Its goal is to provide a more explorative way of browsing the best repository of publicly shared photographs on the Internet.
Features:
Built upon Flashr, a data wrapper for Flickr and Flash created by Kelvinluck
Sort by "interestingness" - Flickr's recent ranking algorithm that puts more popular photos to the top of your search
User tabs allow you to jump from the photos you are viewing to more photos by the user that took them
Related tags along the top of the screen provide jumping points to similar tag searches
You can now save a photo to your Flickr favorites list (authentication requried)
You can quickly link to the photo's page on Flickr
... or to a permalink that brings you back to where you were looking in Flappr
