cuckoo clock speaker
Here's something completely off topic:
This interesting project by French artist Stephane Vigny, is a combination of a cuckoo clock and a giant loud speaker. When the bass is loud, the largest speaker on the bottom is released on a hinge-mechanism and catapulted into the room, retreating back to the cabinet when the sound softens. Although we're not sure if this increases the dance action of the space, it's a cool idea to allow sound to exist as a kinetic object of sorts.
