We need to choose a CAPTCHA image. I'm not entirely sure what would demonstrate the idea of a CAPTCHA well, however I recently took an image that I called "Contemplation" that might fit the bill. 

It would be interesting if we could find an image that visually demonstrated the idea of a CAPTCHA. Hopefully someone has a much better image than mine, as it is rather obscure:
