CCTV’s daring shape definitely grabs attention from anywhere nearby.  But the best quality of its shape is the way it morphs and changes as you move around it in the city.  In that regard, it reminds me of the Pennzoil Building in Houston by Philip Johnson when it was first completed in the mid-1970s.  It, too, was minimalist urban sculpture that employed simple geometries to create dynamic interactions of the forms from different angles.  Koolhaas outdid Johnson, but he is playing the same game.
