Many thanks to Meikel Brandmeyer, whose code (after a one-character typo correction) worked the first time. As soon as I saw it, I understood every line of it; the problem was, it wouldn't have occurred to me to put all those elements (which, individually, I understood) together in just that way. Meikel, thanks again for contributing to a frustrated newcomer's education.
By the way, I recommend comparing the original Java source code to the final version (at http://gist.github.com/369239) to any newcomer who wants to learn how to write Java code within a Clojure program--you don't even have to be interested in Piccolo2D to learn from this. (May you have) Good coding! -- You received this message because you are subscribed to the Google Groups "Clojure" group.
