There's currently an art exhibit at Ogilvie Transportation Center -- formerly known as Northwestern Train Station. Here's some poor shots of the artwork (Blackberry camera, inside, by a guy with a hand tremor). One artist was shamelessly plugging his own work (the "comic book" in two of the later pictures). Seeing this art makes you appreciate the ordinary artifacts of the station, such as the park bench and the oversized trash cans and the display of fresh apples.
Please don't ask me about the metal construction with the TV monitor at the top and the pineapple in the middle. I have no idea.
