What else is done with mirrors???

[P3D Dr. George A. Themelis <fj834@xxxxxxxxxxxxxxxxxxxxx>]

Larry Berlin describes the use of mirrors in a beamsplitting (coming to our
senses Larry? ;) yes, we do like the name!) arrangement to capture 3d with
a single camera:

That's a neat idea Larry!  It's good to see people trying unusual things in
3d.  I will not rush to try it because it appears to me that it leads
itself to prints and not slides and the resulting keystone deformation
might be a problem (?) but I am tempted to ask you and others, what else is
done with mirrors?

I have seen Harold Lloyd's famous self-portrait with two mirrors and
reflections to infinity.  I am sure one can do many tricks with mirrors. 
So, what else is there?

George
