An idea for captcha

Check out the attached image... what if the shapes were randomized, along with a question such as "How many circles do you see?" or "How many objects are yellow?" Would this be easily OCR'd?

I like the idea but it would be easier to OCR than text. Some of the text based captcha's are getting bad. I was trying to search the nvnews forums the other day and their captcha is horrible, it was really hard to tell what it was.

But then I saw another one that I liked some place else, basically it showed a picture of an animal and you had to type in the name of it. e.g. tiger or elephant, etc. I think something like that is a lot better.
