I didnt think of that. Now that you mention it, it does look like coconuts. Looks like it wouldn't take much of a bang to knock it apart though. That one is a little aggressive on the design though, but that is the idea. I wonder how difficult it would be to take a 12" X 4" block of solid Mahogany cut it to a turtle shell shape, carve in the shell sections to make it look like a tortise shell, then hollow out the inside to make the sound chamber, put a neck and top on to build a Uke from that. That, I think would be a fun project. Hmm.. I might need to call a gal that I bought Mahogany from before to make a resonator for my Banjole and see if she can cut me a 12x4 chunk..
