si = 0.5, 1.5, 2.5 … (three step repeating)
Center:-0.291+0.109i; Zoom = 50
Another simple sequence, 1/2, 3/2, 5/2. Most of these, especially the ones with positive exponents have a stable area near 0. There is a high-gradient area near the edge of the stability. Compare with Sequence Fractals Part V #20.
Here the colors suggest a kind of duality between the two areas. Pan and zoom, as well as setting the escape threshold, can be used to find a desired range of cut size and density. Both sides of the chasm have areas the scream out for deeper exploration.
