hectoicosaduohedron is made up of
squares fixed around a pentagon to create a complex pattern of
pentagons, squares, triangles and rhombi. Facets of mirrored or
dichromatic glass taper towards the centre, but stop short of the core.
When viewers look down on one of the square openings, the kaleidoscopic
effect of the reflective glass generates the illusion of a sphere
consisting of squares only. Multiple fragmented coloured reflections
are cast onto the surrounding surfaces.
