Using the application to capture the screen each time the computer is operated, save the work screen using the computer as a lot of image data. Analyze the change in pixel colors of the same coordinates of stored images and form the "marks of creative acts" that disappears as the screen is inherently rewritten freely. Scenes of the digital environment caused by existence of "marks of creative acts" was expressed by two different video. The first video "Build" visualize “marks of creative acts" on the computer screen as convex. This video expresses the view that can be seen by the existence of "marks of creative acts".
