The ESP Game - labelling images

I have just come across the ESP Game while checking the Learning Post RSS feed.
This is a beta project is owned by Carnegie Mellon University and funded partly by the National Science Foundation.

The ESP Game is a two-player game. Each time you play you are randomly paired with another player whose identity you don't know. You can't communicate with your partner, and the only thing you have in common with them is that you can both see the same image. The images presented by the ESP Game are selected at random from the World Wide Web and the goal is to guess what your partner is typing on each image. Once you both type the same word(s), you get a new image.

I have enrolled and given it a try. I found it motivating and fun and it was difficult to close the screen and stop playing... I was however disapointed at the level of vocabulary as to pair quickly and move on, people resort to very basic words. What is interesting however is that at the end of the game you are allowed to see what other people have typed.

I will try it this afternoon with a class of mine if it opens at the school lab and record their reactions.
