Using Grasshopper with RhinoCAM 2012

I hope to start a running discussion of various methods using Grasshopper with RhinoCAM 2012. I'm working on a demo right now using box and surface morphing to generate a textured form for 4-axis machining (see below) that will be on Vimeo shortly. I also hope to show some techniques using Grasshopper to create custom toolpaths and regions, analyze models for undercuts, etc. I look forward to hearing how others are combining these two Rhino powerful plug-ins.
