Mike Clifford made this amazing guitar out of, obviously, LEGO bricks. He used a Les Paul design in vector file format in Fusion 360, a 3D design program, to develop the shape. Then, after building a mold, he poured epoxy over the bricks. Clifford describes the process at Core77:
The most challenging part of this guitar build was creating a solid guitar blank from the Legos and epoxy. I put the Lego bricks on a backplate in a pixelated elliptical pattern. I then put the Legos face down into a partially cured layer of epoxy, then poured more epoxy to halfway cover the Legos. After this epoxy cured, I could remove the backplate that was holding the Legos together, pour more epoxy resin over them to fill in the backs of the Legos. While the epoxy was still fluid, I added a second layer of Legos, and finally came back to fill in the entire form with resin. After I had the epoxy Lego guitar blank, I could just use standard woodworking processes for guitar building, to shape the guitar from the epoxy Lego blank.
It's too bad it's not fully Lego. The Resin stuff is cool but all Lego that you could build on would be fun.
