The folding guitar
This is one clever piece of musical engineering, the DeVillain folding guitar.
The DeVillain works like any ordinary electric guitar but when you get moved on from your regular busking spot you can fold the guitar in half and put it in a normal, if somewhat oversized, bag. When you’re ready to strum your stuff again simply unfold the guitar back to normal and provided you haven’t touch the strings it should still be in tune and ready to play.
More information is available from the DeVillain site.
