I don't think I've taken a clearer shot showing the difference in the way this section of the tower has been cladded. The architect made this easy, every panel is the same. There is only one illusion to be made. They had three sections and got the last one correct. (I know it was the last one because I saw them putting this up/on.) The architect must have been pulling his hair out. The real joke is, no one notices. You can't see the illusion with your eye, it's too big. Probably why it's still winning awards.
