This mesmerizing clip of a bear endlessly climbing a flight of stairs was made to "explore the use of stop frame animation with 3D printing." It took creator DBLG four weeks, 50 frames and an equal number of incrementally different 3D-printed bears to produce Bears on Stairs. The cinematographic technique in the video can be traced back to at least the 1898 stop-motion film called The Humpty Dumpty Circus. It evokes the illusion of movement by playing a sequence of individually photographed shots, each containing an object that has been gradationally moved or changed. DBLG says an extended version of Bears on Stairs is in the works.
