Finding creative commons images

I'm a big fan of Creative Commons Licences. I'm a big fan of flickr CC images. But I find the flickr search interface... not so good.

This flickr search tool, however, is outstanding:

http://flickrcc.bluemountains.net/

In my experience so far, it pulls up a better standard of image than flickr's own search engine - and you don't have to fiddle with the (kind of hard to find) flickr settings for 'search CC only'. It also searches all fields - title, tags, or description - and provides results in order of 'interestingness'. Recommended.
