Blender addon: Assign random vertex colors to connected vertices

Prompted by a request in this BlenderArtists thread I created a small add-on that assigns random vertex colors to regions with connected vertices.

The image shows a single object consisting of several cubes. within each cube all vertices are connected and therefore get the same (but random) color.

Code availability

All functionality of this add-on plus a lot more is now available as a convenient all-in-one add-on on BlenderMarket. It comes with an extensive PDF manual and your purchase will encourage me to develop new Blender add-ons.

The code for the functionality shown in this article is available on GitHub. use File -> User preferences ... -> Addons -> Install from file to install it and don't forget to enable the check box. It will then be available in the Paint menu in Vertex Paint mode.
