Viewr is a Flash web application that uses the Flickr API to dynamically load interesting photos at random, or according to specified parameters. It was designed from the beginning to be as tiny as possible, weighing in at <3kb. Written entirely in Actionscript with zero Flash symbols. Basic customization is available, to refine which images are displayed, and how the user can interact with the movie.
Some of the APIs used in this demo are no longer available, so some features are broken.
