Working on this. The way the Ruby starter pack is written makes it mostly useless, so I ended up rewriting all the map class. I suppose that's what happens when they translate Java to Ruby.
I'm also trying Ruby on Mac OS X and I can't run any java simulations. Always throws a Bad Version number in .class file exception. I think I have the JDK, but anyway the most recent version on the Sun's website is not available for Mac OS X...
