The Art Of illusion
This is another instance of a turning a 2D image into a fractal. It is not simply extrusion. When you create a fractal everything within the image is a fractal. This includes objects, colors, and lighting. In this case I took a 2D photo and transformed it into more vibrant 3D fractal using a heightmap. This shows a more practical use of fractals.
Hint: with fractals you will discover that nothing that exist is flat.
