Until It Dies is a simple game and application engine designed to make it damn easy to get a window up to display all the shiny things you might want to do. It has support loading and drawing images, audio, and text.
UID uses OpenGL to draw graphics, and is built on top of CLOS for flexibility and extensibility.
UID itself is MIT licensed, and all its dependencies use permissive licenses. See below for specifics.

UID is split into several modules. The base system, until-it-dies.base, includes the basics for
the engine, such as windowing, the resource manager, primitive drawing, and colors. If this is all
you need, you can simply load until-it-dies.base. The only dependencies for this base system
are CL-OpenGL, glop, and alexandria.
Besides the base system, UID currently includes systems that provide fancier features, which can optionally be loaded:
until-it-dies.graphics provides image loading, textures, animations, text rendering, and
sprites. It requires DevIL to be installed in the system.
until-it-dies.sound provides positional audio. You must have openal and freealut installed in
order to use this module. This module also depends on cl-openal for bindings.
If you want the whole thing, the until-it-dies.asd system will load everything.
As of right now, all of the modules dump their symbols into the base until-it-dies package. It's recommended that you do not import these symbols into your system, but instead prepend any UID symbols with the UID: nickname.
UID has still not been released, so you're mostly on your own there until the API stabilizes and formal documentation gets written. If you're adventurous and/or curious, check out the examples/ directory for a variety of examples that showcase some of UID's features.
