Currently this requires python-gearman, gearman-java, and a java SDK. This code will probably be all thrown away, but if you really want to play, first compile Biome.java, then run the resulting Biome.class. Note you'll probably need to hack the signatures out of minecraft.jar to get it to run. Then copy grasscolor.png into the cwd, and run gmap.py as usual. It is slowwwww. Perhaps running Biome.class on multiple machines might speed things up? Here's the kind of output produced: http://smp.em32.net/biome_test/
