Description: Mandelbrot in Seahorse Valley with distance estimator coloring. Points less than a pixel from the boundary of the set have a grey applied that depends logarithmically on the distance, effectively (and cheaply!) faking a much higher degree of antialias than was actually used.

Most interesting. I'm stuck with simple iteration count colouring  in Ultrafractal so I don't think I could ever get such evenness of detail from the central 'brot outwards. Care to share the co-ordinates?

Note how even the little lightning bolts of the minibrot are visible, instead of washed out by the surrounding stuff.

Thanks ... it's Seahorse Valley, zoomed into an arm of a seahorse and then into a spiral close to a minibrot along that arm, then down to this microbrot.

The precision is right near the limit of x87 80-bit hardware fp -- a little more zooming (before the minibrot expands to the screen edges) is enough to need software-emulated fp (and distance estimator slows down badly at that point).
