Using a game to describe all the images on the net

ESP Game (reg required, cypherpunks/cypherpunks works) is a game whose objective is to incent English-speaking net users to keyword-label every image on the Internet. The game throws up an image in a Java applet, then asks you and an anonymous "partner" elsewhere on the net to type in keywords until both of you have a word in common — IOW, until you and a stranger can agree on a good label for the picture. Presumably, this is being added to a metadata database for the purpose of cataloguing all the images on the net. Neat idea.
