Whoever gets the gig to rebuild on the site should be an American and not a Muslim (not a "Muslim-American"). I know that's not politically correct, but it's an honest emotion.
The yellow thingy looks like the Beatles' "Yellow Submarine" meets "Star Trek."
The bizzaro-looking black deal that's shown last does at least capture a sense of extreme anger.
The broken-glass effort has possibilities if it could be toned down, and if the proposal wasn't to surround it with same-old, same-old boxy skyscrapers.
The "river runs through it" effort at least has some elegance, which is more than can be said of any of the other designs produced to date.
On the whole, this stuff looks like the drugged-up, fevered imaginations of Hollywierd set designers on a bad day.
