THis is the RhinoScript Blog
Giulio Piacentino and I have been working on an update to the grasshopper/python component and finally have something to show off!!!
http://www.food4rhino.com/project/ghpython - NOTE: Will only work in Rhino 5
This component is a scripting component similar to the VB.NET and C# components that ship with Grasshopper. You get a component where you can define as many input and output variables as you want and then reference these variables in the python script.
