cl-opengl is a set of bindings and utilities for accessing the OpenGL, GLU and GLUT APIs using CFFI.
The examples/ directory contains a couple of examples using cl-glut, cl-opengl and cl-glu. Note, however, that you can use each of these independently. In particular, you can use a windowing toolkit other than (Free)GLUT, if you wish.
