OpenXL is a multiple purpose C open engine. It is a proceduralization library. It can be seen as the artist, the designer, or even the programmer of your project. It is designed so that it has some function power that could turn into any task (performing a texture, a pixel art image, a mesh, a model, a level, a song, etc.). The idea is to play the part of the missing components on your team.
"aura" is a desktop (X root window) background setter. It picks images randomly from specified paths, skipping those that are too small or have inappropriate aspect ratios, and rescales them by cropping solid margins, resizing with cubic interpolation and then the liquid rescale algorithm to fit the desktop with as little quality loss as possible. Images are labelled in the corner using embedded tags. It can changes images on a timed basis or when triggered by SIGHUP or the CLI, and tracks previous and blacklisted images.
