This tower is definitely promising. How sad is it that the mere fact that this proposal isn't a standard SOM glass box thrills me. I do agree with londonlawyer though that even SOM NY can produce some nice stuff if given the right developer and some direction. I can sympathize that it must be tough working with a cheapskate like Mort Zuckerman.
Let's hope this thing get's built. I'd still like to see some more renderings though. I'm not entirely sold on how the top comes together, but I'll give the tower the benefit of the doubt for now. Overall, this thing looks to be a lot more interesting than what I was expecting.
