You forgot the most important aspect of the buildings.
They are completely unadorned and unremarkable except
for two aspects: they're really big and there are two
of them. That's the punchline. The real kicker is that
you're looking up at this massive tower that seems to
have grown full-formed out of the stuff of the city
itself and you marvel with the innocence of a 12yr old
about how amazing it is that man could have created
something of this scale and wonder at the
impossibility of the existence of this object and the
tower replies, 'you know what? there's another one
just like me over there.'
