By all appearances, this website and petition are completely serious:
This proposal submits that one further installation on Columbus Circle would provide additional utility and significance to the circle while maximizing cost-effectiveness: a large-scale compass rose imprinted on the granite plaza between the benches and central monument, thereby forming a ring around the monument that would include arrows and letters indicating north, south, east, and west. Resolved: Upper West Siders have too much time on their hands. (As do we! We totally signed the petition, one of the 4 total signatures so far!)
