Hmm - could be wrong.  Last I heard the 3DFX series ARE programmable.  At
least in the 3D-engine component...
(there are chipsets that are programmable - I was just fishing for
examples)

It's a good idea - now to implement and see how it'd run :)
[the big advantage to OpenGL is an existing API / commandset to start
from]

(aside: My vote goes towards a GGI3D list...  Too many messages annoying
the non-3D crowd)

G'day, eh? :)
