Captcha Alternative using Flickr API with jQuery / JSON

What I came up with (this time) is a system that presents a random Flickr image to a user and asks them to identify the image. I'm going to implement this in PHP and probably create a wordpress, drupal, and elgg plugin. However for now I'm going to create it using JavaScript / jQuery / JSON. This will allow me to create a quick functional prototype that should show if this is a practical method of stopping spam. In addition, I just want to explore the use of Flickr API in jQuery as I think it could have alot of pretty cool uses.
