First we had the Flickr related tag browser
Then we had compfight
Tag Galaxy came to the party
Retrievr added an added dimension by drawing in what you're looking for.
Piclens gave us Flickr in 3D
and who could forget FlickrStorm or Flickr River?
But now, I bring you the flickr finder by colour! Excellent for those obscure coloured presentations!
