The Empreinte de mouvement project renew the location visualization and creates a new city imaginary. Those tridimensional cartographies are results of an experimentation that records the position and it duration of some volunteers during few days or weeks. These records create a movement imprint of each people during these days. The imprint relief highlights the time spent on a territory: the more the spent time is long, the more the relief is important. The playful and poetic dimension of these objects encourage people to live their city differently.
