Nice work.  As I read your initial post, I was wondering whether the inlay would work inside the walnut.  That had the potential to be pretty spectacular.  The black is awesome though.  What kerf did you have to use for the acrylic into acrylic inlays?
Did they give you a graphic file from which to work or did you do a scan and then trace?
 
Thanks!
The acrylic is not inlaid; the red and white are just glued to the surface of the black.  I did a very low-power, high-speed cut onto the black so that I'd know where to glue it.  But to answer your question, I see from my Parameters file that I have a 0.13mm kerf setting for 3mm acrylic (2" lens).
I had to start with a bitmap file, which I traced in Inkscape.  They're working to get me the original .ai file, but the artist is unavailable for the next week, and we wanted the sign for the festival tomorrow.
By the way, walnut is a pain to laser - it's VERY dense, so my "50W" tube struggles with the 1/4" thickness.  The density is also pretty uneven - watch the grain patterns if you're going to try it.  And finally, it's very oily, so it leaves a very sticky smoke residue.  Masking is a must!  But it looks good, so I keep doing it
