Right now I'm working on my MFA at OCADu, and one of the projects that is in progress is this, The Piano Player. The plan for the project is to take an electric chord organ, de-electrify it, and instead power it using a large scale industrial-size balloon... Why? To take the supply of energy/sound (air) coming from a hidden spinning motor, and replace it with something that is physically present in the room.
Oh, and also the piano will play itself, probably playing notes which have been stamped into punchcards. This is part of my wider project to create objects which traverse a sense/nonsense border, in order to create a disjointed and new relationship with bits of technology and nostalgia.
Here is a little demo:
