The image below represents a fractal. One property of a fractal is that it appears similar at all levels of magnification. Try magnifying sections of the image to see repeating patterns. The image is only an approximation of a Mandelbrot set. Precision is limited in order to generate images more quickly. If you repeatedly magnify the image, patterns will eventually degrade due to rounding errors in the software. Without the errors, the patterns would continue to emerge.
