Very nice. Is this the standard mandelbrot? Because your matchmaker images wouldn't have any empty space between the spirals right?
It's the standard Mandelbrot, zoomed into the valleys three times in a row and using an early prototype of what became my multiwave coloring (here only adding a subtle shifting in the blues outside the spirals).
Matchmaker images could have empty space shaped like various Julia basin petals or no empty space at all, depending on the parameters and what the other critical point was doing in the region of the image.
