1. A display, comprising
a substantially transparent substrate, said substrate having at least a first generally planar surface and a second generally
planar surface, the second surface at a first non-zero angle to the first surface;
at least a first reflective element on said first surface, wherein said first reflective element has a first reflectivity
which changes in response to a first signal, said first reflective element comprising a reflective layer movable between at
least a first position and a second position, and a partially reflective layer located between said movable reflective layer
and the first surface; and
at least a second reflective element on said second surface.
