A system may include an enclosure with an exterior wall that defines a cavity therein. The exterior wall may have an interior surface and an exterior surface. A projector support may be insertable into the cavity or may be formed as a single piece with the exterior wall such that the projector support supports a projector in a position and orientation in which the projector projects light at the interior surface from within the cavity. The exterior wall may have a thickness and material composition selected such that, in response to projection of light at the interior surface, an image is visible on the exterior surface.
