Currently my for-fun coding project is Pioneer - a 3D space adventure game with some superficial similarities to various classic space adventure games. It was started (from scratch, in C++, SDL and OpenGL) in June 2008, and I optimistically hope to have it in playable game form by June 2009.

If you want to see how pioneer is progressing then grab the source code from its sourceforge project page.
