Manhattan's Sony Tower, slightly modified, in Minecraft form. Built by Tiresh of Planet Minecraft, it's part of a larger, unreleased city map called The Capitol, which should look damn great when it's done, judging by Tiresh's other builds. Hi-res shots, interior shots, and ingame shots below, map download here.
It looks ok ingame, though it really needs that custom texture pack to work, and there's no "proper" interior, either (because, according to Tiresh, it was created "for the needs of [his] project"). It's quite imposing, at least:
