Within the last year, there has been a proliferation of sculptures in the parks along LSD. I thought this might be part of the BigArt2012 at Navy Pier, but that appears to be limited to Navy Pier. I've not found much beyond a couple comments about the sculptures online. What Project is this a part of? How long will they stay? Where are all the sculptures that are a part of this project? Besides visiting each sculpture, how do you find out the artists?
