Around NYC today–in places like the Financial District, Union Square, and Bedford Avenue–modified pedestrian traffic lights are displaying two orange towers and the message “9/11. Forward. Together.” in place of the usual flashing hand. Created by a group of international students from Miami Ad School Brooklyn, the intervention art is intended “to show people that sharing the memory of 9/11 makes us stronger.”

“People cross paths at crosswalks everyday and don’t realize how much they share with each other just by being in the same place at the same time,” Ece Ciftci, one of the project’s creators, told ANIMAL. “We wanted to remind people that even though a day like 9/11 happened in New York’s history, we’re still here together and moving forward.”
