Clifford Attractor (Pseudo-3D)

A variation of the Clifford Strange Attractor.
In addition to the standard X and Y equations, a Z value is calculated: Z = sin(c * X) * cos(d * Y).
This Z depth dictates the "scale" and brightness of the plotted point. Using the density accumulation technique, this creates a stunning pseudo-3D parallax effect on a pure 2D ASCII grid.
