some text: Believe it or not, these sculptures are actually a water purification device. They pass water through ground-up plastic bottles (among other things) to catch the impurities in water before returning it to the Don River. About a half dozen of these stand on either side of the Don Valley Parkway, which you can see running just behind these figures.
