The Daxophone:
This crazy thing was invented by Hans Reichel, its a friction idiophone, similar to the musical bow, only completely different. Its made up of a thin wooden blade fixed in a wooden block. Theres usually a mic attached, and its usually supported by a tripod. It is often played with a bow, producing a distinguished (and very obnoxious) sound and tone. It can also be struck or plucked. The fretting item in the second pic is used to control the pitch and tone of the instrument.
A wide range of vocal like sounds can be produced on Daxophone. Depending on the shape of the wooden blade (they come in many shapes and sizes) and where it is bowed.
Heres the musical monstrosity in action.
