Jean Jullien, a 27-year-old visual artist tells TMZ when news of the attacks started to spread last night, he needed a way to express himself. He says his first reaction was to draw the symbol of peace and share it as a sign of solidarity ... with the tower serving as an image the world could relate to.
Since then, the image is everywhere ... becoming an unofficial symbol for support. Jullien's first tweet of the drawing has already been shared by almost 50 thousand people and celebs have helped that number grow even bigger.
Fortunately, Jullien's friends and family members are all safe ... he says, "this is an image for everyone, this is a message of peace."
