Germany is one of the better Windows Phone countries, and it seems Microsoft is giving back to the community there.
They held a special event called "Operation: Secret Castle", casting attendees as secret agents. Part of the event was captured by WPArea.de, who posted this video above.
It includes a spectacular 3D light show which now almost seems to be the hallmark of Widows Phone launches all over the world.
The Germany Windows Phone team has been pretty active, recently being involved in a rock festival with Nokia. Hopefully we can see more such action all over the world also.
Thanks Theodor for the tip.
