BlkX2

Double the maximum loop count. Increases the resoluton of the edges of black areas (the actual Mandelbrot set) at the cost of computation speed.

Blk/2

Halve the maximum loop count. Increases the computation speed at the cost of resolution, particularly of the edges of black areas.

(Maximum loop count is shown below buttons, and may also be changed by typing a new value then clicking Run or selecting a new region)
