Nice.  I hope they let us do that next year.

Not beyond what you've got for Ada, you'd have to create your own thick glut
binding as Ted suggested.

If your considering a functional language, maybe Haskell is worth
considering?  It's a nice language and there's a binding for glut available
(http://haskell.org/HOpenGL/ looks like the official site).  There is
atleast compiler available called GHC (Glasgow Haskell Compiler), and an
interpreter Hugs.  I don't know if the binding works with hugs or GHC, you'd
need to check.

Running a search for OCaml and opengl on google with give you quite a few
hits, you'd need to judge for yourself what you need.
