Curious what others think about the animated gif CAPTCHAs from http://hellocaptcha.com/ and how hard they would be to crack.

It looks like they aren't accessible to blind or low-vision people, so I'm going to discourage you from using them in any case. I might add color-blind too for some of them. Clever, but inaccessible.
