I came away from NAMM this year thinking that epoxy-infused woods were going to be the next big thing. I saw tons of them, and many were incredibly creative.
The one in this picture was probably the best of them all. It's a little hard to see, but the wood has been cut into tiny little cubes, which are falling away into the "void" of the epoxy. I talked to the builder about how he accomplished it. Suffice it to say it was incredibly painstaking and time-consuming. The guitar was not cheap, but the results were breathtaking.
If all that is not enough, also check out the fretboard inlay....and note how the very end of the fretboard also has little cubes of wood falling into the body!
