Affine Transformation

Football

A    spheroid pulled at the poles
—a pointedly comedic effect—
can wobble or flip when thrown,
or easily slip from the grip,
and any bounce from the ground is completely unknown.
But keep these features in check,
and spiral this prolated shape
of dimpled pigskin when letting it rip:
then lo and behold, the rotational ellipse
arcs through the sky with grace:
zen of quadric face.
