This is definitly no sundial, not even a projection dial. If it was
the (shadow)lines should be curved.
However the idea could be used to make a nice projection sundial.

Have any of you see this odd structure in the Giardini at the 2007
Venice Biennale? I'm trying to figure out how this might function
as a sundial. If it is a sundial, it might be classified as a
stained glass projection dial. My best guess is that when the
colored projected image of the circle is centered on the white
circular surface on the ground, that this is some significant time
and date. Any ideas?
