The images in order are Aqua Tower in Chicago (Jean Gang), Brick Weave House in Chicago (Jean Gang), St. Ignatius Chapel in Seattle (Stephen Holl), and the proposed Port Authority Terminal in New York (Santiago Calatrava). In the case of Aqua and the terminal, I liked how the architects were able to combine sinuous curves and straight lines. The Brick Weave house seems like a great example of perforation and separation between structure and envelope. Stephen Holl's chapel is really cool for the way he uses reflected light (the pictures really don't do it justice).
