One of the objectives of Meisenthal’s workshop was to find a simple movement that would be easy to reproduce so that artisans working in glass could easily create objects without knowledge of the project. This installation intends to pay homage to this principle. The spectator comes into contact with one of the realisations through a simple and intuitive movement: slipping a coin into a money box. The installation aims to extract this idea of a simple gesture and reposition it at the heart of a collective creation. Although its transparency means that glass is a material often used for practical and visual purposes, its acoustic qualities are neglected. When we insert a coin into the money box, we immediately hear the glass vibrating. As if it were a machine that we have recharged, the other money boxes that have been installed emit a reverberating sound, via solenoids concealed in the shelving. These repeated sounds immerse the spectator in an acoustic landscape produced by vibrating glass.
