These first two pictures are of the Robie House by Frank Lloyd Wright in Hyde Park near the University of Chicago.  The house was being repaired, hence the signs in the yard and the boards in the top-story windows.

Not all my pictures were of buildings. <-- Left: the building was ugly, but the purple of the plants kinda matched with the purple on the building.  Right: A plaque near the location of the world's first controlled nuclear chain reaction at UChicago. -->

This is the Wrigley building, near the start of the boat tour I took. -->

These are both the same building: the picture on the right is a close-up of the top.

Above left: A bridge house at one of the many draw-bridges.  Above right: A non-operational bridge, permanently up at an angle.  I deliberately lined up the picture with the bridge instead of the ground.

Right: the reflections on this building are really cool. -->

<-- Left: probably my favorite building on the whole tour.  Maybe that was because it was so hard to get a good shot.  :)  The edge of the Sears building is the black thing on the left. 

Right: One of three Montgomery Ward buildings on the tour.  It was deliberately constructed such that no one could have a corner office.  -->

<-- Left: I think I just took a picture here because of the thing at the top.

Right: Some industrial thing near the end of one leg of the tour.  Even the smokestack buildings here look neat. -->

<-- Left:  One side of the NBC building.

Right: I never got a good shot of the building with the diagonals. -->

<-- Left: I like this picture a lot.  The tall building was originaly faced with white Carrera marble. But the marble began to crack, and there was worry some would fall off.  So the entire facing was removed.  They couldn't get any more Carrera marble, so they re-faced it with North Carolina white granite.  The building cost $100 million; the re-facing $85 million.

Right: This building used to be for cold storage.  It was later converted to condominiums.  The windows are somewhat small, as they were initially bashed into the sides with a wrecking ball, which was kind of hard to do. -->

^ Above: Unattractive in my opinion, but unusual and interesting-looking.

<-- Immediate left: Another picture I took just because of the oddity at the top. 

Right: Another really neat looking building.  The top is somewhat Gothic, and the rest is somewhat modern. -->

These last three are all in Millennium Park.
