They've been building it in fits and starts for several years. I've long wondered what was going on there. The usual sorts of "coming soon" signs, and "financing by" signs, are nowhere to be seen.
It's near another big commercial building that was supposed to become the home for some aspect of the New York "nanotechnology initiative," which yielded a gigantic facility in Albany, but (as far as I can tell) little else.
No wonder I never saw it.
