Found this on Slate: An interesting proposal for a World Trade Center memorial by Fred Bernstein, an architecture writer (for the NYTimes, among others, it seems). Basically, it's twin tower-sized piers with the names of those killed placed on the appropriate "floor." The piers would be oriented toward Ellis and Liberty islands.
While I'm dubious of the mirror-like conceptual similarity to Maya Lin's Viet Nam memorial, which we visited last weekend (i.e., the orientation, the name placement mechanism), the simplicity and outside-the-Bathtub siting/thinking are very welcome. [q: Why is there no search function on NewYorker.com?] I will not discuss (or link to) the hothouse proposals on display at Max Protetch Gallery.
