Well I could work with the colors and specular values a bit.
I think I used the same colors values as ldview, but picked
my own specular values based on empirical testing. I think
I used different specular values for silver, so it may look
different from that angle. You get a better impression of
the shininess when you spin the brick, but I guess that's
not what we're looking for here.
I'm surprised you missed the references to 334 and 383 in stub.c.
If you look at the code you'll notice the comment above those
lines says something about Gold, Silver, and Electrical contacts.
Maybe Travis could look at that section of code in stub.c and give
some suggestions for material properties to make the metal really
gleam. Or I could try to find it in the ldview sources again. To
be honest, the bricks don't look particularly shiny to me when I
load them up in ldview either. At least not until I spin them.
It's probably due to the default position of the light source.

It uses a different opengl extension, but it does work (or at least
it did work the last time I tried it.) I haven't figured out how
to do this for the Mac versions yet :(
