13 Here are the jMonkeyEngine "Hello" programs translated to clojure.
15 * Hello Simple App
16 Here is the hello world example for jme3 in clojure. It's a more or
17 less direct translation from the java source [[http://jmonkeyengine.org/wiki/doku.php/jme3:beginner:hello_simpleapplication][here]].
19 Of note is the fact that since we don't have access to the
20 =AssetManager= via extendig =SimpleApplication=, we have to build one
21 ourselves.
