Musca is a simple window manager for X allowing both tiling and stacking modes. It is similar to ratpoison but more friendly to the mouse and using a simpler keyboard navigation. There are no built in status bars, panels, or window decorations save for thin window borders to indicate focus. Window navigation can be mouse click to focus or entirely keyboard driven. Window tiling is manual but simple, and there are no restrictions on how you divide up the screen. It uses dwm's dmenu utility for launching apps and running various built in commands not mapped to hot keys.

The CRT X-Y Library (libcrtxy) allows you to write vector-based video games (like Asteroids, Lunar Lander, and Battlezone from the 1970s and 80s). The end-user (and/or packager of your software) determines how lines are rendered, depending on the capabilities of their system. This choice includes anti-aliasing, alpha blending, blurring, and even the display size and depth. Fixed-point math is used, and sine and cosine trigonometric functions (using look-up tables) are provided. The library is based on libSDL and uses SDL as the video backend.
