Yeah, I really wouldn't know--This project was mostly concerned
with color depth extension.

Yes, thank you for making sure, though. I actually have a
Matrox P650, which is like the baby brother of the Parhelia--
It has their 30-bit "GigaColor", also. But, unfortunately . . .
  o I don't believe there's currently much OS or software
      support for 30-bit color. (Outside of Windows's
      DirectX 8+, anyway?)
  o No 30-bit color on nearly all of today's LCDs, as far as
      I can tell.

But with the synthesized 30-bit color that this project dealt
with, none of that really matters, right? =)

Thank you for checking about the Matrox deal, though,
- Ron
