Slickrframe turns your iPad into a Flickr photo frame. By default, it shows you the most recent pictures uploaded to Flickr, but you can also view pictures based on specific tags. Soon, you'll be able to view photos from your Flickr friends as well.
Photos update every 3 minutes.
Slickrframe is also available for any internet-connected device with a modern browser and an internet connection at http://slickrframe.com
