This is an anisotropic material that uses a sierpinski squares pattern. It is completely procedural and has __NOT OSL__ code. So it is available for GPU rendering. It is a cycles version of [my OSL material](http://elbrujodelatribu.blogspot.com/2013/05/blender-cycles-osl-sierpinski-squares.html).

I have included 5 presets and their renders.

The model has been made by Robin Marin (@tuqueque). I have used the 2.61 bleder test version. You can download it [here](http://www.blender.org/development/release-logs/blender-261/blender-261-demo-files/). It was created to test materials and it is a CC-BY lincensed blend.

Enjoy it!

EDIT: Now it uses new Module option in Math node instead own Module node group.
