As visitors approach Halo, the cylindrical form is pierced at the base by arches of varying sizes. These archways produce glimpses into the interior of Halo and unexpected cantilevers as they intersect the simple exterior form.

The stark difference between the simple exterior and faceted interior gives the impression that visitors have entered a geode.
