World IPv6 Launch Day

Well, I was on vacation last week, and realized upon my return that I'd missed World IPv6 Launch Day on June 6. Gee, 6/6. Good thing it was 2012 and not 2006 (666). I wonder if anyone did something special to celebrate. Based on sales of books such as Security in an IPv6 Environment and Handbook of IPv4 to IPv6 Transition: Methodologies for Institutional and Corporate Networks, either no one cares or it's very simple.
