The red one is glass, although it isn't real obvious.  Hmm...

Well... good luck!

he is right!  Replace the torus from the "a" with a chrome sphere! :)

Not a bad idea, actually...  I'd have to retexture the "g", since that's
chrome right now.  Hmm...  Now I know what I'm doing this weekend!  :-)

Hmmm, no offence, but the "g" has a too high ambient or diffuse (or both), or
maybe a too low brilliance to look like chrome...
And I'd put in a no_image background sphere to give something to reflect...

Hmm...  After looking at the picture again, I think the texture may be good, but
the white reflection doesn't really look good...

Yeys, add a sky_sphere (or your chosen 'sky' method) and make the plane
no_reflection.

This definitely needs something to reflect and maybe some more glass
objects. Right now many of the letters look like bits of fabric pasted onto
a board.
