"A floating tidemill on the UK's River Tyne has been filled with "electro-acoustic musical machinery," powered by the river itself. The building, a collaboration between Owl Project and Ed Carter, called Flow, is 'a floating building on the River Tyne that generates its own power using a tidal water wheel.'
The acoustic machines inside, powered by CNC-milled wooden gears and timber pistons, 'respond directly to the ever-changing state of the river. The sounds created by each instrument can also be manipulated by visitors to the millhouse.'
Specifically, the floating auditorium includes 'three inter-connected sonic instruments which mix traditional craft and digital innovation. They draw water from the River Tyne, passing it through a series filters, lasers and sensors, which bubble, beep, hiss, creak and groan.'..."
