When Candy Chang lost someone she loved very much, she thought about death a lot. She wanted to know what was important to the people around her. So with help from old and new friends, she turned the side of an abandoned house in her neighborhood in New Orleans into a giant chalkboard and stenciled it with the sentence “Before I die I want to _______.” so anyone walking by can pick up a piece of chalk, reflect on their lives, and share their personal aspirations in public space.

It was all an experiment. By the next day the wall was entirely filled out and it kept growing.
