Allegro for Improved OpenSource Project (Score 1)

I think the Allegro project (founded by Shawn Hargreaves) deserves the award for improved opensource project. For anybody who doesn't know, Allegro is an awesome cross-platform game library. Personally, I've used Allegro for projects at work, because of the portability, not just games. Programs written with Allegro will compile and run under Linux (svgalib, framebuffer, or X11), Windows, DOS, or BeOS.

You should check it out for yourself.
