Michael G. Kaplan writes “CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) are commonly used to prevent computers from filling out web forms. Computer vision experts have been able to design programs to foil CAPTCHA with a high degree of success.
I have designed a CAPTCHA that is based on the identification of attributes contained in an image generated by the grouping of easily recognized 3-D objects. I call this the Virtual Photographic CAPTCHA and it is likely to remain invulnerable to automated attack for many years to come. A novel anti-spam system necessitated its development.”

Looks like you will have even more bleeding edge content to incorporate now, Les
This system looks very promising in weeding out those comment spammers that so plague blogs and forums to date. I find the concept very intriguing and wonder why it took this long for some genius to figure out that bots can be trained to read simple 2-D images, but are nowhere near capable of deciphering 3-D images (yet).
