The headline blurb from the website;
"Welcome to the wallofdeliverables.com, a companion site for the IA Summit Wall of Deliverables annual event and an ongoing repository of deliverables submitted from the community to share. Take a look around, be inspired, and let us know what else you’d like to see!"
At the website you'll see a number of innovative ways of presenting business/software requirements.
There are a few intersting things there already, but you could probably help out by adding some of your creative and brilliant work.
