Interactive "tagging" format

hi there, here’s an effect that i’ve been seeing quite a bit lately and i’m wondering if it’s even done in flash…or if it’s done in another language entirely. if you click on this site: kuler.adobe.com and then select one of the color schemes, a bunch of words will come up for each scheme under the color blocks in the off-right side of the page. then by clicking on one of those words, it would take you to search results for yet even more color schemes that relate to that word. does anyone know of any tutorials to create an interactive tag gallery such as this? and if so, is it done in actionscript or another langauge.

thanks in advance,
denise
