Glad to see the Firefly initiative is taking a more serious shape today @ale2x72 tweeted about its new version which I have to say looks great they have created a hole bunch of new components also they have moved the project to this this Firefly Experiments website , Something good to share with all of you who are interested in the development of Grasshopper and Arduino.
Description (from the sit)
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.
