An "A Ha" moment is serendipity writ large whenever an idea, coming out of the blue, solves a wicked problem in elegant fashion, something Google did by rethinking CAPTCHA and turning it into an concise one click solution to thwart bots and spammers by simply enabling one to click the checkbox I am not a Robot, instead of trying to figure out nonsensical words displayed in often confusing and ugly ways. To yours truly, this is akin to This sentence is false, a logic bomb conundrum Kurt Godel used to great advantage when coming up with his revolutionary Incompleteness Theorem. ReCaptcha, a very cool approach to a noisome problem, will change the net for the better. :)
