The Brillolin

Played against a table.

The Brillolin (as would norwegian or german readers understand) is made of spectacle frames, with no glass lenses in them. They are put on the nose and fastened with a strap around the neck. Through them go two guitar strings to a tiny miniature violin with a built-in contact microphone. On the violin, there are protruding pieces of piano wire and two wooden tongues, all contributing to the noise-making range this instrument has, usually with a bow.
