Heartless Machine by Christopher Locke; Walk The Plank is an acoustic impedance coupler. The horn is supported by a single long piece of steel, welded to a single long (and very heavy) base. There's a delightful springiness that echoes the tone arm on a vintage turntable. This horn will make the sound from your iPhone louder and richer, using no electricity, wires, plugs, or batteries. The shape of the horn is enough to add 25 decibels or more.
