I'm totally not cool enough to think of something like this on my own... Seth has a little experiment happening over on his blog where Mother Nature is his co-pilot. The Disintegration Collaboration features artists from around the world who are leaving bundles of paper in the elements for a few months to see what happens. We don't have exciting elements here....maybe some wind...a little drizzle...so who knows what I will end up with on May 1.
I hung my wire cage up in a palm tree. You should try it too! All you need is a before photo and an after photo. Have fun!
