This morning, while I walked from the tramway to my office, I spotted some communal dumpsters for glass-bottles and the like placed at the curbside. The steel dumpsters are about man-height and their bases are octagons. They look very raw and blocky. My immediate involuntary thoughts were: “The corrugated-steel texture looks good, but hell, they surely could have used some more polygons!” Now am I a mapper, or what?
