A game involving windows, their grilles and surfaces: the darkness of the crosses contrasts with the lightness of the panes. The crossbars are almost constantly in motion, sometimes as a single bar, sometimes as a group of several, and finally as a single bar. The moving crosses resemble film strips at times, but then they turn in a circle or shift and reveal the outside world: trees, bushes, or the sky. The images move faster and more frantically, superimposing on top of each other until they are interrupted at the end by individual freeze frames.
