2: "Sine" Julia-set variations

There's auseful page by Paul Bourke and Tim Meehan about the "sin-variant" Julia set, at http://local.wasp.uwa.edu.au/~pbourke/fractals/sinjulia/ , exploring z --> c × sin(z). As with the normal Julia set images, we can adjust the four values that make up the components of c and the initial value components of z, to get a range of images.

....

This function gives nice repeating ribbon-like fractals. As before, setting parameter D to zero generates shapes with mirror-symmetry, but higher or lower values cause the shape to break up and twist clockwise or anticlockwise:
