I've been fascinated by the perceptual relationship between objects and the shadows they cast for a long time. The simplex or tetrahedron is an efficient means of demonstrating how this stereoptic relationship works. Richard Harrington, March 2014.

This three-dimensional projection of a Sierpinksi Sieve fractal generates moiré patterns as it randomly rotates on its horizontal axis. It is a set of 15 progressively larger tetrahedra made from three ¾″ edged cells (the smallest that can be assembled from the screen) to 1 1/2″, 3″, 6″, and finally three cells that are 1′ per edge. The diaphanous property of this material creates a stereoptic “dialogue” between the object and its shadow. This geometric progression also displays the chiral “handedness” of this structure- implying that a dual symmetrical mirror of the object can be built on its horizontal axis, and that two additional mirrored objects could be constructed on their vertical axes.
