Before I Die...
Making a checklist before you kick the bucket is "of course." Slap on your shoes, point to the stars, take a running start and kick the shit out of that bucket. But OHH, 'kicking the bucket' is DYING, in some places here or another.
"Candy Chang," according to her website, "is a public installation artist, designer, urban planner, and co-founder of Civic Center who likes to make cities more comfortable for people." Most of her stuff is very interactive, inviting the public to spread their ideas in a directed way. She lays out a basic idea and gives the rest up to you. Pretty rad.
In this installation in New Orleans, Chang took an abandoned house and put a big ol' chalkboard on the side of it. Big lettered spray paint across the top reads, "Before I Die..." and is then repeated in smaller imitations to fill the side of the building with 80 blanks. Chalk was provided in the little baskets and the rest was to be seen. 'Fore long, literally a day, the entire board was filled. And the magic about chalk is you can erase it with a quick wash and open up the canvas for the next bunch. The installation went up this past February and, last updated May 5, 2011, is still going strong.
Here's the project's website with a list of every entry, endless photos, and an explanation of the project. It's off the Civic Center site, of which Chang is the co-founder.

That was sick
