The main subject embraces findings related to formulations by Feynman, Virginia Woolf, Singh and Botticelli. An optional title could be sub-structures and Kangaroo fractals. The prefix sub refers to a part of something larger and both finite values and differentials appear, as well as general areas, together with script for Octave Online. The Kangaroo was recognised already by Monthy Pyton and here due to its parental fractal. Other animals occuring are Humming birds, to illustrate hoovering, and a Duck in foam. Production of foam is described with functions: Energy transported in a curly, whirly flow is related to an area measure. The figure 3.284277537307, found in the RMB-bifurcation, is revealed, and applications for light are proposed. About noncircular orbits:"Interesting and made me think 'twice again'.""The method of deducing materialization for non-round orbits with the eccentricity zone is possible to use even in agriculture, thanks to the connection with the language of mathematics. Congratulations!!"
