Together the exterior form and skin and the interior spaces attempt to give the building's identity an "oscillating character", in the words of the architects. This character is achieved through the use of the three glass profiles outside and the relationship of the visitor to the horizontal tubes and vertical supports inside, as well as the view out through the windows. The glass acts as an eye between the city and the store, and vice-versa, sometimes distorting and sometimes focusing the view. The intended oscillation is most apparent through the concave and convex panels, each creating an effect different than the typical flat glass. Prada..................................Tokyo, Japan
