To fold Julia fractal you only need to treat it like something simple and two-dimensional, project it onto a square grid, transform that grid, and then interpolate every cell using simple affine transformations. EDIT: Removed unneeded emotional junk EDIT 2: Affine transformations are just simple arithmetic operations between complex and dual numbers but nevertherless matrices are simpler!
