Stalking display

A "for rent" sign that follows you around.

With all the OOH on the streets, it’s not a big surprise many people stroll on by without a second glance. Enter the moving “for rent” sign designed by Niklas Roy in Sherbrooke, Que. A computer program tracks pedestrians as they pass by and the “À LOUER” sign slides along beside them, prompting some passersby to interact with it (consequently prompting us to wonder where the hidden actor is to point at the hidden camera like in those Just For Laughs gags).
