Imagine you are hiking along, headed up a hill and
when you look up you see a gigantic tissue floating
to the ground.



You close your eyes and shake your head, but when you
open them again it is still there, floating . . .



Wait, this can't be real. It certainly doesn't look real.
It looks like a drawing. How can a drawing be sitting
at top of the hill?

As you approach, you realize it is made of metal.
It's a sculpture, made of welded and painted steel that
looks like a two dimensional cartoon drawing of a three
dimensional piece of paper ... that is three dimensional
if you get close, but looks two dimensional if you stay
at the bottom of the hill...

Well, wasn't that a nice little mind trip?
