Above is a version of the famous clock, done in glass by Seattle glass artisans.
Here are some photos of the flower show on the first floor. Flamingos and the color pink featured prominently in all of the displays.
Below are some photos of the store's other cool features. I think there are ten or twelve different floors of merchandise....and the famous Walnut Room restaurant, as well (sadly, we didn't have time or funds to eat there).
Below is the the famed Tiffany Ceiling on the 5th floor. It was built in 1907 and is absolutely stunning when seen in person. There is a visitor's center on the 7th floor (which has a nice display that highlights the store's place in Chicago history) and the kind folks there were happy to point me in the right direction.
Below is a close-up detail of some of the ceiling tilework.
I couldn't resist putting this last photo in (below). We got distracted for a little while by the FAO Schwartz toy section and these awesomely large (probably 6-8 feet?) stuffed creatures. We checked out some of the prices, and let's just say that these will not be going home with us anytime soon. I suppose we don't really have space in our apartment for them, anyway.
