I just love how easy it is to explore problems like this with Clojure and then use Incanter go get some cute little plot too! :-)

Update: Incanter’s author David Liebke sent me a version of the above that fits into one tweet and another one with a Latex annotation! I updated my code to incorporate some of his suggestions.
