Welcome to the home of Subsentient. My noteworthy open source projects:

The Epoch Init System, init system for Linux, designed for user control, unintrusiveness, and efficiency.

Bricktick, Arkanoid/Breakout/brick attack implementation for ncurses written in ANSI C.

WZBlue, GTK+ lobby monitor for Warzone 2100. Written in C, runs on Linux, Unix, Windows, etc.

Warzone 2100, a multiplatform FOSS RTS. I play a LOT of this, like at least once a day, and I'm a code contributor.
