It would be interresting if someone with one of these faces would
photograph the face in stereo using light sources from different angles
and then mount some regular and some psuedo.  Would you get a normal
looking face at all times (or never) if mounted psuedo? Does the light
have to be from below to get a normal face when mounted normal? Maybe
even some side shots to see if the mask looks away ( or towards if
mounted psuedo)?
