Bioscope, A Hand-Cranked Digital Video Viewer
Bioscope is a handheld digital video viewer which the user operates with a hand crank. Depending on which direction the crank is rotated, the user can watch the video forward or backward, in one-frame increments. The device is inspired by an early movie projector of the same name. Bioscope was created back in 2012 by Jon Stam and Simon de Bakker.
