My personal favorite sundial is at the Cranbrook Academy of Art, Bloomfield
Hills, Michigan, about six miles north of Detroit.    It sits outside the
Science museum by a lovely pond.   It has only one moving piece.  Imagine a
saucer, tipped to corresppond withi local latitude, with a cobra-like arm
extending from its lowest point and curving along an arc that would meet its
high point, 180 degrees opposite, but stopping 3/4ths the way.   Where the arm
ends there is a small hole.   You turn this saucer-snake so that the sun
shining through the hole hits an analemma scribed on the inner part of the arm
just above the point where the arm starts.   The correct local time is then
indicated by an arrow on the saucer pointing to the correct time inscribed on
its base (in equidistant daytime hours).
