I’ve just uploaded a new tutorial based around the grasshopper plug-in for rhino, Louver Tutorial.  For those who don’t know about grasshopper, visit this link (Grasshopper).  In short, grasshopper is a plug-in for rhino that is used to generate parametric objects.  Its more or less a playground for creating relationships between geometries.  In the tutorial, I explain by example how to decompose a surface in order to map points along it.  These points become the start of a louver system, in which all kinds of relationships could be created to organize their generation.
