I forgot to tell that, 2 or 3 months ago, I joined the team of Mars, Land of No Mercy an Open Source Turn Based Strategy Game, available for Windows, Linux, BSD and Mac OS X.
My roles are 2D Graphics Designer or 3D Modeler (if I would be able), and Mac OS X package maintainer.
A demo version, for all platforms supported, is available at download page here.
For people interested in compile by themself sources package and SVN trunk are available here.
For particular instruction to compile on Mac OS X, ask me.
Here my first sketch for a mech concept.
