The Extreme Tux Racer project - https://sourceforge.net/projects/extremetuxracer/- is looking for developers, and, in particular, someone to lead the effort going forward.
ETR is a high speed arctic racing game based on Tux Racer.
The project is developed in C and C++.
Because the original development team has largely disbanded, you should probably get in touch with me - firstname.lastname@example.org - and I'll make the necessary introductions.
What direction is the project heading towards? Just so you know, I don't necessarily want to be a lead programmer (I would rather be an assistant programmer), but if you need one I could give it a shot.
