Hmm... I like the inside idea. The configurable performances spaces seem like a good idea. The outside though.... kinda like a glowing borg cube... I'm sure the actual façade will look a lot better in person, because that render looks pretty ugly. Also, I feel like putting a giant glowing cube next to the already glowing cube base of 1 WTC and across the street from the equally bright at night blue glow from the lobby of 1 WTC is a bad idea...
That open plaza between this building at 1 WTC is just screaming to house Koening's Sphere... I can't think of a more perfect location for it.
