Dust Garden Prism

The Burning Ship map z -> (|Re z| + i|Im z|)^2 + c iterated over the parameter plane, framed at c = -1.81015 - 0.004243i with half-width 4e-06 on the Cantor-fine dust that sits on a ship's mast. Inside a dust band the smooth count moves tens of iterations per sub-sample, so the count is averaged over the whole supersample block before it picks a hue while the distance estimate stays per sub-sample. The count is then histogram-equalised over lit pixels only.
