Nacho from SEW points to an excellent site that uses Google's image results in Flash to create a guessing game. The object is to determine, as quickly as possible, what the query is that produced the given image results. The game is fast-paced, addivtive, and very revealing. It's a nice way to think about Google's image technology and get a good feel for how well it really works.

The game is called - Guess the Google, and it creator, Grant Robinson, has a terrific site of his own where he points to several other interesting projects.
