The contest seems a really nice idea with an effort put to it, considering that it even has some prizes! Btw, Marc, are you giving away your own cash or is it some sort of community share?

However, since it requires to run on Linux, it enforces the usage of OpenGL, which hurts all those who work with Direct3D on Windoze. Feels like having a Microsoft flavor added to it, but on the Linux part. Why not relaxing the platform requirement a bit, but giving big extra points for every additional supported platform? I mean, you are not promoting a commercial product, but a development freedom, right?

My few cents...
