*mario837 has had some fun playing with a few of the included sample parameters in MB3D so I thought I would give it a run as well. This is a combination of two of the sample files, ThePearl and TreePlanet. It's a DE combinate... I only did a little tweaking and adjusting, replacing the _Rpow3 with the TreePlanet formula...
