Subway Tunnel Moire Wall

The Zhonglou Mole Wall is a landscape art installation composed of an inner pattern and an outer perforated plate, which is made by CNC laser cutting technology and multi-frame image stacking technology, using the principle of visual persistence. The middle of the two-layer board is illuminated by LED light strips. When people walk by, the originally static image will present a dynamic effect under the influence of visual illusions.

The unique feature of this product is that it interacts with people passively. The double-layer board makes people outside a certain line of sight have a visual illusion, and through the principle of visual persistence, the originally static picture presents a dynamic effect when the observer walks. The changing speed of the picture depends on the speed of people walking.
