This is a timewasting experiment with Flickr.
Simply enter a search term and see what photos people uploaded and which tags they used on these photos.
Click any of the tags to see what other photos were uploaded with this tag and which other tags were used on
those and so on and so forth.
Click any photo thumbnail to see a bigger version and click the bigger version to return to the thumbnails.
This experiment works with JSON and the flicker RSS feed API, no Ajax involved!
Animation and other bells and whistles are provided by the YUI.
