Last Friday, a Facebook friend shared about a Mandelbrot set interactive application which might be useful to advanced mathematics students. The online app can be used to explore the Mandelbrot set. The user can change the colors and the number of iterations. Images created with the app can also be saved as a png file — mine is shown below.

For those who are not familiar with fractals, loosely speaking, they are some sort of patterns of similarity. I will not elaborate about it here because I am planning to write about it later.
