This wallpaper, designed by Studio Carnovsky, changes images depending on what color light you view it under. As such, it could be an incredibly interesting thing to experiment with in other contexts—including outdoor urban lighting, public signage, and even film animation.
In the latter case, imagine a hallway whose wallpaper is printed with six or seven closely related scenes from an animated clip; each “scene” is printed in a different color. A light programmed to move through the appropriate sequence of color changes is then installed in the same corridor; as it flashes from color to color, changing perhaps every half-second, you see what appears to be a moving image on the walls around you.
It would be a kind of unmoving zoetrope—a stationary cinema in printed form (or a stationary cinema in stationery form?).
Even if only used for interior decoration, however, the effect is well worth exploring further.
