Define Gravity... In A Sculpture.

This sculpture is situated outside the parliament buildings in Tokyo city. To be honest, I thought it was pretty boring at first, although the geometric, cubist inspired form does compliment the modern atmosphere with the skyscrapers towering over you. But then I noticed them spin. Each one spins a full 360 randomly in the wind, taking different forms and shapes as it changes with every movement. The balance and equal spinning ability of each rectangular piece is all based on precise centre of gravity. One main reason I think I didn't initially like the structure was also due the cheap, metallic material used. I soon changed my mind however, as the sun glistened on it with every angle as it spun slowly in the wind.
