Hi Roni, the algorithm is implemented there using the "Grasshopper" node system in Rhino.

There is a similar node system for MoI called "Elephant", there are some details on it at http://moi3d.com/wiki/nodeeditor .

But that is a separate thing than the actual implementation of the Voronoi generator itself though, that looks like a quite extensive node structure. I am not aware of an existing implementation of that in the MoI node editor.
