Yeah, the example I was basing my code off of may have been from cl-sdl, 
since it used both SDL and OpenGL.  In the past, I've used SDL and 
OpenGL in conjunction, but I can probably get away with just using  
http://github.com/3b/cl-opengl without SDL as it looks like it 
implements gluProject and gluUnProject and I don't need SDL.

Thanks!
