1. A projection device, comprising:
one or more light sources;
a rippled substrate defining a reflective surface, wherein at least part of the directed light is directed toward a furthest rear portion of the projection device such that at least one light source of the one or more light sources is directed perpendicular to the furthest rear portion of the projection device, the reflective surface configured to reflect light source light from the one or more light sources directed at it as reflected light; and
a first lenticular lens configured to receive the reflected light from the reflective surface;
wherein the reflected light received by the first lenticular lens generates a three-dimensional lit image.
