An extensive series of photographs of Lucio Celis's round glasses projecting a shadow with the movement of light, made it possible to build a video of this long photographic sequence. The image is presented as a blue negative copy, typical of copies of architectural plans. Celis's futuristic vision is represented by his round glasses, which have become an icon of many authors such as Le Corbusier, Philip Johnson or IM Pei, and in this case they come out of the face and become an archetype, as if an architecture in question, bathed by the path of the sun on its surfaces.
