London-based aritst Katy Beveridge was looking into a way to film animation in realtime when she developed this project based on her research into the history of animation techniques. The bicycle animation can only be view through a camera operating at a high shutter speed, or else it is all just a blur.
Basically the camera, when filming, takes 25 photographs every second, so when the wheel rotates say 30 degrees each time the frame is replaced by the frame that occurred previously. The degree of rotation necessary is dependent on the number of frames you have around the wheel. ~ Katy Beveridge
