Tetrahedron molds a triploid 3d curve.

red = axis . . . . blue = grid . . . . black = models

Grid projects along different axes for visual effect.

Is there significance in the circle resulting from a solid tetrahedron ? (Something besides the 'Peace' metaphor?)

Note that all grid squares vary in size with perspective projections, in contrast to the axonometric projection which sizes all grid squares equally.

How Was It Molded ?

The 3d CAD software used , ( "formZ" ), draws equilateral tetrahedrons in two clicks. Then the spline drawing tool is used and set up to 'anchor' on the 6 mid points of the 6 edges of the tetrahedron., while drawing a continuous, closed curve. This software was adjusted to close the curve, which means to connect the starting point with the ending point while smoothing out the curve to equal parameters in the rest of the curve.
