Pixel Art Library (http://common-lisp.net/project/pal/) is an MIT licensed
OpenGL accelerated 2d graphics library for people who want an easy and
efficient access to interactive graphics and sound. In a nutshell, games
and other graphically heavy applications.
Currently it should run on Linux and Windows on most Common Lisps that
support CFFI, bug reports are both feared and welcome.
