This is a heartwarming and ingenious idea. Candy Chang (http://candychang.com/before-i-die-in-nola/) describes this project on her blog:
It’s easy to get caught in the day-to-day and forget what really matters to you. With support from old and new friends, I turned the side of an abandoned house in my neighborhood into a giant chalkboard to invite my neighbors to remember and share what is important to them. Before I Die transforms neglected spaces into constructive ones where we can learn the hopes and aspirations of the people around us.
