Musgrave Texture in Cycles by Example

Gottfried Hofmann writes:

The Musgrave texture in Cycles can yield interesting results. But unfortunately it is also very unstable, so often one gets just white or black. That's why BlenderDiplom created thousands of test-renders you can use as reference and also a video showing interesting settings. The test-renders are available for download in a .zip file. The article also features some technical details on this kinda complicated texture.
