A new add-on to generate snowflake shapes using fractal algorithms is now available for download.

I recently heard about a cool web-app created by Italian programmer Marco Cameriero, that creates 2D Koch Snowflake shapes.
After reading a bit about these fractals in Wikipedia, I decided to create a script for generating such structures in Blender.
The script generates an edge loop in the shape of a Koch Snowflake fractal, that you can then use for... whatever your imagination can come up with! (mine is leading me in particular to 3D printing cool snowflake like shapes).
To install, download the script from GitHub.
You can set the radius, the basic polygonal shape the snowflake is created from, and the number of fractal iterations. For detailed installation and usage instructions, see the Wiki page.
And if you're interested in the Python scripting and development process behind this plugin, read the dedicated blog post here.
Here's an example of a model created based on a Snowflake curve:
