Great Grails opensource application I could learn from [closed]

Question

I love to learn new and better ways to program from good opensource applications written in desired language/using such technology. Now I am digging into Grails and I didn't succeded in searching great and usable opensource application written in Grails. I tried googlecode, github and even the community page on grails documentation webpage. Find nothing really top quality application (missing documentation, too simple and so on). Maybe I missed some, but maybe users of grails have their loved famous app. Could someone recommend me any?

Thank you.
