A speed bump by a school in Canada is getting decorated with a two dimensional trompe-l’œil of a young girl chasing a ball. When drivers get closer to the speed bump, the girl’s elongated form "appears to rise from the ground as cars approach, reaching 3D realism at around 100 feet, and then returning to 2D distortion once cars pass that ideal viewing distance," according to Discover Magazine. As you can see, it's pretty convincing, except that Pavement Patty's sneakers are bigger than her head, and for some reason she's playing by herself in a parking garage. Maybe that's how Canadian kids get their kicks?

The speed bump is being tested this week, and police will monitor the illusion's impact on drivers. Here in NYC, speed bumps are a hot-button issue in some neighborhoods; you'll recall that Staten Island residents requesting a speed bump got so fed up with the DOT's foot dragging that they made their own DIY bump. (The DOT then sent a bulldozer to raze it.) And in Philadelphia a couple of years ago, the city installed a speed bump with fake 3D spikes jabbing out of it. If the Canadian experiment proves successful, maybe NYC DOT commissioner Janette Sadik-Khan will consider painting some Pavement Pattys down here! Of course, to get New Yorkers to stop it'll need to be painted onto a bollard.
