This is a program which renders the mandelbrot set without the need for variables. It simply makes the function call itself with the new z parameters until the escape condition is met. It is best to render the set on turbowarp due to its ability to compile blockly (the programming language scratch uses) into javascript (the programming language browsers use), use this link to get there: https://turbowarp.org/1027520031?fps=60
The third and fourth power multibrot are able to be calculated as well, click see inside and look below the function to see the 2 sets set up to be rendered.
