Neat idea, skillfully executed, from artist Scott Garner, who writes:
On the hardware side is a custom-framed television connected to a rotating mount from Ergomart. Attached to the back of the television is a spatial sensor from Phidgets, makers of fine USB sensors. On the software side is a simple C application to communicate with the sensor and feed the data to a Unity 3D scene. The scene itself consists of a camera tied to the sensor data with all lights and objects parented to it so they rotate in unison.
