Aluminum wall clock: the time is the dimension in which we conceive and measure the passage of events, according to Immanuel Kant it is "a form of human sensibility". The time is the perception of motion and it is constantly changing in relation to the space. Momento is an object that changes the image of itself based on the variation of time. The aluminum panel contains the movement and it can be fixed on the wall in 4 positions (vertical and horizontal). The hands modify the proportions of the object creating, every single moment, a form in continuous transformation.
