Google Image Labeler

This is kind of an addictive game-type activity Google has come up with to help create image tags for their search results. You are paired with an anonymous partner for 2 minutes. You both look at the same images, one at a time and try to come up with labels for each one. You get points if you and your partner's labels match. Interesting way for Google to get people to help create image tags...
