I made a small Cocoon web shop, long ago, and made it available free,
through CocoonWiki. (http://wiki.apache.org/cocoon/ExampleApps)

Over a period of time, I received many mails thanking me for the application.
I have to work on improving the shop application. I will work on it, once I find time.

Here are some screenshots:
1. Shop Home page
2. Shop TV click
3. Shop Bike click
