If you haven’t seen “the Bean” at Millennium Park (which is actually by Anish Kapoor and called Cloud Gate) you should. It’s damn cool. Don’t go until summer, it’s undergoing work right now, and besides, it’s cold here.
But when you do go, be careful what pictures you take:

Karen Ryan, press director for the park’s project director:
“The copyrights for the enhancements in Millennium Park are owned by the artist who created them. As such, anyone reproducing the works, especially for commercial purposes, needs the permission of that artist.”
