Named after the variation whose rotation provides the main structural movement. Also featuring, as guest appearances, sinusoidal, pie, uncube and julia (in her wedge form).
Technical: the major challenge was to smoothly transition the X-dimension of the bipolar transform whilst
rotating. This meant dropping the simple rotate(-1) command and replacing with explicit values for the coefficients defined as converted from polar coordinates (i.e. of the form Transform.coefs[0,0] := rx*cos(cx*pi/180); where rx is the changing length of the line OX and cx is the angle).
