This weekend the Croatian LUG had an event in Varaždin in a large school sports hall.
The poster is in Croatian, but I think it looks interesting anyway:

We set it up in record time (13.5 hours, ending at 4AM, most of us stayed there to sleep). You can see in the official pics of the setup how zombified we all were by the end:

There were 1040 visitors in total, and the ticket price was 2 dollars, so we also made some money (most of which was spent for the space and transport).
