Interesting image searcher

Sprixi is a new search engine for public-domain and commercially-usable-creative-commons images. it mostly draws from Flickr and some sort of PD clipart source, so it's not like Google Images, but it has the great advantage that you can use (sometimes with appropriate credit) everything you see. And the interface is very nicely usable: much much better than Google Images.
