One simple yet interesting early work was entitled Device for Architectural Inversion (1979). The work was facilitated by the simple technology of a pair of glasses that had two mirrors affixed to the front at 45-degree angles. When a participant wore the glasses, it appeared that they were walking on the ceiling. Thus a strange conflation of actual space with a displacement of actual space was facilitated. The participant experienced an uncanny sense of architectural displacement. Perhaps this work is a proto-Virtual Reality work, or augmented reality through reality displacement.
