`Honestly, I’ve considered doing this before, but placed it above my personal level of expertise. Someone, or a group of someone’s in or around the University of Toronto has figured out how to hack the construction signs and is using them for environmental messages. Not only the ones shown here proclaiming “Don’t Drive” and “Take Your SUV Back to Detroit” but also advertising a campus event on sustainability.
I’m impressed. Rumor has it that a campus activist group, Cars Off Campus, is responsible. But I sure hope no one gets in trouble for that rumor.’
with a link to a video aswell.
