While you're at trying viewing devices, try M. C. Escher's image reversing
viewer which swaps left and right views of your surroundings by using two
right angled prisms. (See page 79 of *Stereogram*, from Cadence Books) It's
weird but it works. It's like looking at a parallel view using cross eyed
techniques. I wonder if the mind would learn to re-interpret the left and
right side views (and the corresponding reversal of the sense of near vs.
far parallax) if the prisms were worn long enough? I'm sure that would be
very disorienting!

The device that turns the world upside down is another type of prism. I've
seen them and even made one for myself but don't remember the specific name
of it. Perhaps someone on the list knows the type of prism I'm referring too?
