Bird Of Prey Bronze

The cubic Burning Ship map z -> (|Re z| + i|Im z|)^3 + c iterated over the parameter plane. The set is exactly bilaterally symmetric about the line Im c = -Re c, so the sampling frame is turned 45 degrees to stand that mirror upright. Luminance is an exterior distance estimate carried on the exact real 2 by 2 Jacobian, since the absolute values make the map non-holomorphic. Body shading is each orbit's closest approach to the origin and the feather plates are the iteration at which it happened.
