This is a zoom into the center of the "dragon" from the previous Mandelbrot set plot, "Fractal Sheep dragon."
This plot is at a width of 3.6e-14. (This is about the limit of the magnification of Mandelbrot plots you can get using double precision before floating point rounding errors start to seriously degrade your images)
