When the question gets old enough (7 days I think) I will click 'start a bounty' and offer up 300 points. Add the 50 bonus points that the site tacks on and the answer with the most votes when the bounty expires picks up a cool 350 rep and a link from http://soapi.info.
Use whatever tools and libraries float your boat, jquery, mootools, dojo etc, but interaction with the API must be driven by Soapi.JS.
Good luck and may the most ridiculous app win. ;-)
NOTE Time allowing, I will be happy to answer any questions about the library and help out with code if you get stuck. Simply post an answer describing your problem and any relevant code.
