425 Park Avenue

I'm at the MAS Summit today (visit my twitter feed for some occasional updates), where renderings and models for the 425 Park Avenue invited competition are on display. Norman Foster's winning design was unveiled a couple weeks ago, but I had yet to see the designs of the three other competitors—Zaha Hadid, OMA, Richard Rogers. So here they are.
