Firefly is a set of comprehensive software tools dedicated to bridging the gap between Grasshopper (a free plug-in for Rhino), the Arduino micro-controller, the internet and beyond. It allows near real-time data flow between the digital and physical worlds, and will read/write data to/from internet feeds, remote sensors and more. It also includes a Pachube reader.
WeaverBird is the plug-in for topological transformations in Rhino and Grasshopper. It now supports colors and texture coordinates. It helps inventing, smoothing, modifying, thickening and preparing meshes for rapid manufacturing technologies.
