I want to combine Manipulate with ManbelbrotSetPlot just to get Mathematica to give me a quick and dirty Mandelbrot Zoomer. I want to be able to single/double click on a section, and have it zoom in on that section. All I've been able to get is an adjustable viewing window, but that's really not satisfactory. I imagine a Locator might do the trick, but I'm unsure how to get it to work. How might I accomplish this?
