.aperture
Two identical unit device combinations are suspended separately in upper and lower spaces of a building. If people or motion are present, they continuously send and receive images of their respective locations to each other, creating an 'aperture' between them. The devices have simultaneity and versatility both in their functions and in their construction. They can have their reception switched so that they send and receive to themselves [digital 'mirrors']. In addition, the same object in two contrasting installation orientations yields differing perceptions.
