Brent, Here's the mockup with proposed materials:

The red is a pearloid material that matches the red in the 12th fret inlay. For the globe, I tried several combinations, and found the paua shell sea and mop continents to give enough contrast to be useful. We could go all pearloid if you want to keep the blue/green style. Bob says I can't pull the tape off yet, but here's the mock up of the 12th fret inlay:

The actual inlay wound up having slightly less detail, after all, it is pretty small! Let me know what you think about the oval inlay and we'll get crackin' on it.
