The Difference Engine #3 uses the architecture of the ZKM Media Museum as a 3D template and the visitors to the museum as the interface. It is an interactive, multi-user, sculpture about surveillance, voyeurism, digital absorption and spiritual transformation of the body.
The Difference Engine #3 was inspired by Charles Babbage's original Difference Engine # 1 (commonly considered the world's first computer). The original machine was used to calculate numerical positions. This piece calculates the captured image and position in the physical/virtual space of visitors to a physical space, located now at The ZKM Media Museum.
