We did a version of the human auth tag - the major advantage being that it's accessible. It only uses 2 images, so bots have a 50/50 chance of getting it right - but since we can't use captcha, 50% less spam is better than nothing.
It's pretty similar to Jacobs, except it asks the user to select a nature picture, and the alt text then has words that a sight-impaired user would able to logically deduce fit the criteria. For example: glassy lake vs. telephone. Ours uses a back-end home-grown "content server" cfc (to get around sandbox issues) - so it's not very sharable as is - but if anyone wants to try to take what we did and make it more open-source-ish, you'd be welcome to do that.
