Voronoi Cell Formation

Hourglass

 

The videos below shows a plexiglass box full of sand, with holes on the bottom. As the sand comes out, cones are formed, it is like an hourglass with many holes. The resulting shape on the surface of the sand is a Voronoi grid. The roofscape of the interiors in the Hourglass is like the sand. It is comprised of adjacent polygonic cones, with a circular hole at their apex.

Apex

 

The skylights at the apex open creating an effective passive ventilation system. A black out device is placed under each skylight. It is a mechanism that works like the shutter of a camera lens. For ambient illumination, a circular metal disc suspended under the apex conceals a linear light.
