For flickrers - can be very time consuming if you like browsing pictures... http://www.airtightinteractive.com/projects/related_tag_browser/app/ I also got myself a flickr account. I didn't do much with it yet, I only packed a few pictures in it that you know already from the Random Photohtread. Holler if I can add you, though!
Hmm, nice interface, simple and easy to use... a little long to load, but there are a lot of pics each time...
