Mechanical Mirrors:
The 4 mechanical mirrors are made of various materials but share the same behavior and interaction; any person standing in front of one of these pieces is instantly reflected on its surface. The mechanical mirrors all have video cameras, motors and computers on board and produce a soothing sound as the viewer interacts with them.
