It looks to me like the building was made too brutal and now has lost its self control, projecting outward waves of brutality that break up the clouds and sky, squeezing them, trying to force them into cubic spaces so that the brutality may be at peace.

But the brutality can never be at peace - how then could it be brutal?  So it would simply be accumulating energy from the brutalized cloud and sky, awaiting its assault upon moon and sun.

I am that brutality, I who ponder cloud and sky, and moon and sun, and smile.
