Three ornate windows are located at the back of the chapel (the front of the building), but they are surprisingly difficult to photograph. They are above the lobby. You can't see them very well in the chapel unless you're farther away (otherwise they get covered up by the clock and lobby wall). Basically, I had to stand a long ways away, zoom in all the way, and get the best pictures I could, but the quality definitely suffered as a result--I apologize!
The middle window is a beehive; the ones on the sides are sego lilies.
These are beautiful windows, and they're probably meant to be appreciated more from the outside (when the windows are illuminated from within the building) than from the inside (since you can only really see them from the rostrum, and not very well at that).
