without the benefit of Freud, knew exactly what they were doing when they used such sexually suggestive symbols.

From a Freudian perspective, the animations above are indeed suggestive in a number of respects, whether with respect to fantasies associated with breasts, cleavage, buttocks or intercourse. Pscychologist Galdino Pranzarone is variously cited as asserting that the origin of the heart symbol was probably the shape of human female buttocks seen from the rear, and not an actual heart (Getting to the Bottom of Valentine's Day, Fox News, 16 February 2006). Thus the Greek goddess of beauty, Aphrodite, was beautiful all over, but was unique in that her buttocks were especially beautiful: Her shapely, rounded hemispheres were so appreciated by the Greeks that they built a special temple to Aphrodite Kallipygos,earlier discussion of Cognitive heart dynamics framed by two tori in 3D (2016) drew attention to Wolfgang Daeumler's comments on the presentation of Lissajous curves on the surface of the horn torus (featured above), as illustrated by the animation below. The visual form of these curves is often suggestive of a three-dimensional knot, and indeed many kinds of knots, including those known as Lissajous knots, project to the plane as Lissajous figures.

NB: Whilst potentially interesting in its own right, the otherwise annoying flicker in the animation on the right is a consequence of the simplistic method of its development. With greater effort the blue and green curves could be presented in the same frame raher than in successive frames

As noted above with respect to some phases in a
