I’d wondered about those signs, too, but I have to admit the actual explanation is a little disappointing. If it’s supposed to be commuter-empathetic art, it’s kind of goofy, uninteresting commuter-empathetic art. But maybe I’m just jaded from reading too much art theory this semester - I used to think Warhol was kind of fun, but if I ever see another Brillo box, I can’t be held responsible for my actions.
