Seems there is no texture support, I tried this code on faith:
GLFW.loadTexture2D "eric.tga"
and no dice... looked closer and it really looks like GLFW-b doesn't
support it, which I am sure i read somewhere.
How *easy* would it be to add it... I have played with FFI, tried to do a
wrapper around the Wii libwiimote library but gave up after managing to
open and close a handle.
I better start reading the source I guess, I am sure it won't be that hard
to follow the pattern...
Thanks,
Sean.

In case anybody else nedds it, I found a "solution" here...
https://github.com/dagit/nehe-tuts/blob/master/lesson06.hs
So I guess I can continue my tinkering and understanding of how more
talented Haskell hackers do their thing...

Can anyone point me in the direction of some explanatory material on the
motivation behind empty data declarations? I have read the GHC manual on this,
but am none the wiser for it. Googling does not seem to turn up much either,
although I may not have tried hard enough.
When and why might this language extension be useful?

You could start here:
https://github.com/yairchu/red-black-tree/blob/master/RedBlackTree.hs
The big picture is defining constants.
A declaration like "data Bool = True | False" defines constants at the
term-level. Terms are always typed.
A declaration like "data Z" defines constants at the type-level. Types
are always kinded, typically of kind * (what Z is). The recent
introduction of a Constraint kind expands the possibilities of
type-level programming. Same for polymorphic kinds.
