Horizon

[Pauldelbrot]

This may at first look like a glitch. A perfectly straight line, surrounded by fractal shapes? But I assure you it is not. The zooms will be spectacular, but don't hold your breath; the depth and iterations preclude any image in this area being done in less than a couple of days at least.

There's a layer with a logmap stretched over the whole iteration range and a layer with a linear colormap that repeats every 90 iterations: the number of iterations increased across each tier of seahorses. The latter layer is used to bring out the filaments by brightening the red in waves.
