This
building is more than an optical illusion. Standing
in front of it gives you the sense that it is going
to fall over on you, while at the same time conveying
a sense of strength and superiority. It is a seven-story
upside-down pyramid. Five levels of the pyramid are
above ground, two more are beneath the surface. Each
floor is nine-feet wider than the one below it. Standing
close to the base, you can actually look up at people
working in their offices above.
