I saw this while browsing around the internet, it seems like quite a simple Idea and is far easier to use than the current system of typing words. But I do remember earlier this year a company came up with a concept of having simple games the user had to play to complete their CAPTCHA, I'm pretty sure that within a week someone had written a program that managed to complete the games with a fairly high success rate. So I was wondering what some of the more knowledgeable members of HN thought? would something like this be easy to bypass with a computer program or is it really as secure as they believe it is?
In some ways I do hope it is secure as it does seem like something I would implement on my website especially is their conversion rates are accurate.
