There is one principle in the world on screen. It is the principle of construction. Unfinished or abandoned buildings are regarded errors and starts to debug for maintenance of order. However, there is a movement to deviate from the principles of construction-universe. The images start to blend the time and space of the abandoned building and the information of the space under construction. Eventually, the combined data causes errors, and those combined images and sounds attempts to leap out of the flat world of the screen.
