Magnification in a 2D-slice of the four dimensional cubic parameter space using the standard parameterizing z -> z^3 - 3a^2 z + b, critical points z = +a and z = -a. In fact this motive is a further magnification in the earlier deviation "Bloody Dragon-jaw" [link] .

*a_real = #pixel
*a_imag = #pixel
*b_real = -0.7345
*b_imag = 0

Both M+ and M- are displayed one in each layer.

No filters or post processing except anti-aliasing.
