Here's a pretty great out-of-home execution for Oliver Stone's upcoming film Snowden, about the NSA whistleblower Edward Snowden—a billboard that's been spying on pedestrians in Toronto and streaming footage of their movements on the street.
Snowden's revelations about the NSA, of course, raised troubling questions about mass surveillance. And the billboard—timed to the Toronto International Film Festival, where Stone's movie premiered—itself embodies those very issues.
DentsuBos and Elevation Pictures set up surveillance cameras with motion tracking technology around Dundas Square. The cameras tracked pedestrians' movements and livestreamed them onto a giant video board.
