For centuries the Chinese used paper covered wooden lattice grilles in their windows. The lattice was often painted in black or dark red lacquer and decorated with gilt flowers and ornament. As the paper was translucent it was the shadow of the lattice design that was the window feature instead of actual views of the outside world.
