Each letter is created individually then unioned together to create the entire
logo. The macro that makes the logo takes one arguement, which is the amount to
shrink the border of each individual letter, then makes a one-unit deep complete
logo. I used multiple scaled and translated copies of the complete logo unioned
and differenced together to make the beveled edges and indented center, as well
as the "invisible" extruded walls intended to enhance the glowing radiosity
effect. the "no_image" tag is applied to the entire extrusion just before being
unioned with the visible logo. If you're interested, I would be happy to make a
simplified demo scene and post the code.

As a side note, I used the same technique with height_fields and the invisible
extruded walls did in fact have a radiosity effect on the visible height_field,
similar to the "I" in the logo.
