Here is more information on the 'Cosmic Mudra' of Zazen then you probably wanted.
There are the traditional interpretations ...
But then there's Dogen Zenji's likely interpretation ...
"Hey, folks, ya gotta do something with your hands!"
Then place the right hand over the left foot, and place the left hand on the right palm. The thumbs meet and support each other. Just sit upright, not leaning to the left, inclining to the right, slouching forward, or arching backward. It is vital that the ears vis-a-vis the shoulders, and the nose vis-a-vis the navel, are directed away from each other. Let the tongue spread against the roof of the mouth. Let the lips and teeth come together. The eyes should be kept open. Let the breath pass imperceptibly through the nose. [NISHIJIMA]
Note: Apparently, the signal was dropped in the last minutes. So, there are no closing bells.
Please self-time if you are sitting with the video.
