[plt-scheme] game libraries

I/m considering a project that uses Debian, the allegro game library, 
OpenGL, and the allegro plugin for OpenGL (which I haven't yet found in 
Debian -- help welcome).  I plan to work in an exploratory style -- 
try something, see what's fun about it, refactor, build on what works 
and discard what doesn't.

Of course I'd like to try all this using Scheme.

Has anyone done this combination before?
Does Scheme talk to the OpenGL plugin for allegro?  I've been told 
     Scheme talks to allegro and OlenGL separatels, but together?
Even 3D graphics should be fast enough if I have OpenGL doing the 
     heavy lifting.  Any dissent?

Have you any advice as to how I should go about this?

And, of course,

Should I be using some completely different collection of tools or 
libraries instead?
