The XO WORLD PROJECT, created by Daniel Anderson, features two sculptures, "XO PLAY" and "XO WORLD," that encourage peace and love around the world. "XO PLAY," on display in the Oculus through late October, depicts children playing a game of jacks—symbolizing childhood innocence and harmony with the world.

"XO WORLD," on display just outside One World Trade Center at West Plaza for 18 months, features a 12-foot "Jack" from the game of Jacks with an "X" representing "love" in universal sign language and "O" representing the world.
