The flow machine, by movement and sound, creates a project with the intention of the space to be coloured and to live again – more specifically to enhance a route from the building’ s static and silence to life. The operation is based on chain drive. Along the chain hanging parts of metal produce sound ,due to their impact in the containers .Finally, their passage through the containers, leaves traces of paint on a canvas that is placed to the floor, between a door and a chair.
