Diplopiascope v.1 2013
Prerecorded stereoscopic films that can be controlled by by the viewer. The videos of the drummer and the shrine gate pathways were shot with two cameras from a fixed position. The videos were then looped and projected independently. To simulate stereoscopic 3D, they are viewed through a mirror device, the left eye being shown the footage from the left camera, the right eye the footage from the right.
The viewer controls the speed and direction of the films via simple controllers attached to arduinos, one for each hand/ film.

Because of the changing speeds of the videos, the stationary objects (the drum set, wooden frame, cones, walls, etc.) are seen in crisp stereoscopic 3D, however, the moving objects (the drummer, people, etc.) will be seen in double. This produces a strange effect as the we switch uncontrollably between the information we perceive, jumping randomly from the left eye to the right dominating perception. The moving objects take on a very strange phantom-like presence in the realness of their solid stereoscopic surroundings. While the majority of the field of view remains fixed in crisp 3D, the figure of the drummer seems to jump in and out of time frames and consciousness itself.
