This simple website will create a random fractal that will hopefully be pretty. You can see more information regarding fractals at the bottom of the page. You can generate as many as you please. Please be aware that the larger the max size, the longer it will take to generate the fractal, and the more memory required (obviously, but still warning you).

All fractals will be a square. The "Max fractal size" setting will set the maximum size, in pixels, for both the width AND height of the randomly generated fractal (remember, it's the setting for the maximum size, not the exact size, so you may get smaller results). Sizes above 10000 are not currently allowed. I recommend a size between 1000 to 3000 for the best results, and a size less than 1000 if you want quick but less detailed results.

What is a fractal?

A Julia set, a famous fractal

Fractals are abstract geometric objects that contain detailed and "rough" structure at arbitrary scales. That is, if you were to continuously zoom in on a fractal, you would never reach the end of it. Fractals go on infinitely. Many fractals have a beautiful characteristic that they are self-similar at smaller scales, meaning that they are built up of infinitely many smaller and identical versions of themselves. Unfortunately, notice how I specified that they are abstract objects. They only go on infinitely long in our heads, and all images of fractals in physical existence do eventually end (as far as we know). However, don't let that spoil the fun. If the image of the fractal is detailed enough, our eyes won't be able to immediately tell that there is indeed an end to the so-called fractal. If the eyes are not able to detect it right away, then who cares?

Famous fractals include the Mandelbrot set, the Sierpinski triangle , and the Sierpinski carpet (this website sometimes generates the Sierpinski carpet, but with some color!!!), but many more exist.
