Due to the defeat of their client, Mussolini, in WW II, the project was never realized and became one of the best known unbuilt modern projects. Through the use of advanced computer graphics technology, an attempt has been made to simulate a walk-through experience of light and materials inside this unbuilt monument. This animated representation revealed two of the important spatial characters embedded in the design of this building: a constant oscillation of dark and light as well as that of closed and open.
