End the CAPTCHA Agony

End the CAPTCHA Agony | Are You a Human.

Haven’t encountered one of their challenges yet, but looks a like novel solution to the CAPTCHA problem (make text hard enough for a computer to try to decipher, but not hard enough to be annoying to real humans.)  Instead of having human to try to read some obscured text, give them a simple game to play.   HTML5 with a fallback for flash, nice!
