YOYcats
Endless LOLcat fun, not, with a new image generated at a click of the Refresh button, thanks to the boffins at Carnegie Mellon University, like they had nothing better to do.
The results are generally crap, even by the low standards of LOLcats. And I can't imagine snarfing images off Flickr and generating some SMS text was a major compsci breakthrough.
Maybe we should call them WTFcats.
