以公开发行的“中学生广播体操示范教学”影像资料为素材，截取其中一段影像并将其处理成快慢两个视频，分别通过两台显像管视频显示器播放，视频显示器直接放在地上，屏幕朝上，上方分别有一个悬挂着学生赴（衣、裤）的马达装置，马达匀速正反运转，使学生服在显示器屏幕上方上下运动，间隙与屏幕接触：两个显示器（被改变线路，由单芯片控制改变其色彩，反差）屏幕被学生服每接触一次，其图像效果（色彩、反差）即变化一次。
Using publicly available "Middle School Broadcast Gymnastics Demonstration Teaching" video footage as material, a segment is extracted and processed into two versions: one fast and one slow. These are played back on two cathode-ray tube video monitors placed directly on the floor with screens facing upward. Above each monitor, a motor device is suspended, evenly rotating in forward and reverse directions, causing a student uniform (shirt and pants) to move up and down over the screen, intermittently touching it. The monitors (modified with altered circuitry, controlled by a single chip to change their color and contrast) experience a change in image effect (color, contrast) each time the student uniform makes contact with the screen.
