Similar to the Tirana house-painting project, 2003, this floor pattern is a two-dimensional manifestation of the quasi brick. (The quasi brick is a twelve-sided polyhedron, based on naturally occurring quasicrystals, that utilizes both four- and fivefold symmetry.) The pattern of the stone floor is made using four different types of volcanic rock – dolerite, rhyolite, blue basalt, and oiled black basalt. The ceiling is lined with mirrors that reflect the floor as well as the visitors.
