One of the 3D fractals that I like very much is the Menger sponge.
As the name suggests, it was discovered by Sir Karl Menger at the end of the twenties.
The implementation of this fractal has more things in common with the IFS (iterated function system) than with the Mandelbrot formulas.
At the bottom let me show you some original picture that were inspired by the Menger Sponge.
Some of the pictures have a fractal background created with JWildfire.
