Two bikes rotating simultaneously to create this animation. the frames are really rough cut as this is still early days in the test. This is shot on my cannon 550D dslr and is filmed at 25 fps (normal film speed) no manipulation has been done to this film off camera. Though you do need to be recording this in order for the animation to be visible, the naked eye just sees this as a blurry rotation. This is because of the frame rate of the camera and the speed at which the wheel is rotating.
