This piece was computer numerically machined from program code generated by the sculptor from his Mathematica™ master code. The physical parts were cut from a series of 2" x 2" x 2" cubes of high density foam, the texture arises from kerfs left from a ball end mill programmed to be tangent to the explicit lemniscate minimal surface of Celso Costa. The piece exhibits hands on D₄ symmetry by assembling the eight D₄ symmetric cuboid elements into a fully assembled Costa surface form.
