One day in April 2012 I made a video of the bunker, the site for calling the dragon, and edited it into The Bunker (22 min) and The Bunker (short) (4 min 10 sec.).
As in other years I called the dragon for a day and night as well, at three-hour intervals from 2 February 2013 at 3 pm to 3 February at 3 pm, not on the roof of the bunker, but on the slope near the main building. The material was edited into Day and Night of the Dragon 1-3 (19 min 30 sec).
I called the dragon also by waving a green ribbon from the roof of the bunker towards the north with the camera on the vievpoint hill and from the viewpoint hill towards the south with the camera on the roof of the bunker. These nearly invisible performances were edited into Calling the Dragon - Waving (A&B) (21 min 40 sec).
