Hi, thanks - I spent quite a bit of time tweaking the depth and lighting in this piece, so I'm stoked you noticedMandelbulb3D is a freeware 3D modeling program that's specifically designed for 3d interpretation of fractal equations, primarily the mandelbrot set (as I understand it). So, instead of working by constructing meshes, you work by inputting and tweaking formulas. I also use height maps and colour maps that are created in either Photoshop CC, Stirling2 (a 2D fractal engine) or both.
