if you play the 5 sec clip of Sir Foster talking about his design for CITC at the link below, you will see many vertical elements in the façade, something that does not show up in the other renderings I've seen so far. This is the model he is using to represent the building and if this is a more accurate representation of the building then is even more industrial even futuristic than I thought. You may or may not like this, I do because it reflects even more than I though how revolutionary this building is.
