The New York Times has published an amazing interactive look at a conceptual project for ground zero, developed by well-known architechts unsatisfied with the city's efforts so far. This article describes the project illustrated by the flash presentation (click image).

The architects criticize the process put in place to develop the new ground zero plan, saying that it's too bureaucratic and doesn't involve architects at the fundamental stages where they really need to be involved. They came up with the plan as a hypothetical scenario just to see what they could do together. It involves a memorial at the actual site, two huge twisting towers adjacent, a number of museums, and the conversion of a huge length of West St. into a long park and pedestrian mall.

This plan sounds orders of magnitude better to me than any I've seen yet. I'm sure the entire plan would never get made, for political and other reasons, but maybe the city will be smart enough to at least consider some of the ideas... particularly the towers. :)
