I would love to see an idea like "Project Honeycomb" be implemented in the Revit family editor. Zach Kron previewed this internal plugin at RTCNA14 and it looked awesome!! This would further expand the Dynamo to Revit infrastructure, just like Dynamo player.
Embedded computational logic in families would be infinitely powerful!
