I would like to see a demo of that. Even the most simple approach in pushing Java into the direction of a "game development" environment is a step in the right direction IMHO.
I mean how much impressive games are there for Java? One hand is enough to count them all.
So good luck with your project!!!

Not that it would really matter, but i can't find that setTransparentColor() method you mentioned. Did you forget to add it or am i blind?
