Here is a test of the optical flow component of Firefly. You can check the Firefly add-on to Grasshopper here. As an ongoing research project, I’ve been searching for a suitable platform to study responsive geometric patterns. This initial study focuses on one particular effect of Firefly, the optical flow that outputs the direction vectors on a given webcam input. I developed traces of it by joining endpoints of these vectors together, creating strings. Then, recorded them to give better motion effects, adding color afterwards. Here is the Grasshopper definition […]

I finally installed Firefly, it immediately powers Grasshopper up with beautifully smart components, even if you don’t have ardunio it is still very useful. If you want to give it a try, first you have to install a small tool free from in order to send data to Firefly. After that, you may download and install firefly from their website, It was the real-time inputs, my first interest. I was very excited to get data from my laptop’s tiny webcam and process that data to deform a pattern. […]
