Hi all,
The code included below in a computer running radeon shows up a
projection of a cube, in a computer running nvidia shows up nothing. I'd
please ask you to run it and reply to the list saying if it happens to
you too. If you know why please explain me... I'm really not
understanding why.

So, he wrote it all in Lisp!
