The Mobile Dune

The mobile dune carries a projector that projects the mouth into the hollow spherical blackboard. In the first act of 'A play in three acts that might once but most probably will never be performed, on humanity's attempts to understand (and possibly conquer) the world', humanity drags truth, that is carried by the mobile dune with decorative beachgrass, across the beach-stage to draw a model of the kosmos. The mobile dune is often called the beamer mountain.
