This came out of me needing an excuse to write some Clojure, and wanting to model a simple coin-tossing game. What started as a guide to Clojure for busy programmers probably makes a right-sized holiday hacking project.
Thanks Lio. Let me know what you think. Also, I got rid of the background. Seems my evil plan to hypnotize the population of HN might not actually work out.
(One side point, that background is a little hard to read against; it actually started to give me a headache... :)
