What does Chicago offer architecturally?

What is Chicago offering the world of architecture right now? This city has for most of the last century been on the vanguard of that field--the first skyscraper, the first modernist skyscraper, the tallest building in the world, etc, etc--but for about three decades, it seems as if we've been sleeping. The 90s saw the cutting edge of architectural design move to Asia and the Middle East; within the last few years, some Western cities have picked up too. (London and New York come to mind, two cities with several absolutely breathtaking projects proposed or underway.) Where does that leave us? We're just beginning to emerge from the period in which we scarred River North with a few dozen concrete cookie-cutter condos. Is anything going on right now in this city that the world is looking at and taking notes on? Will there be in the near future? Millennium Park certainly comes to mind. Maybe the rest of the forum can add to that list.>
