ajax tag cloud and links

I have begun working on a project that creates a tag cloud where words are entered through a simple form on a separate page. The most recent words are colored red, and the more often a word has been entered the larger its font. I would like to adapt and expand the attached scripts. Details, images and scripts are found in the file linked and zipped below. ## Deliverables please see attached .zip for additional details, images, and code.
