This time I show the prototyping process for one of my newest works, “Lines” is the second phase of “Circle Lines” wich was the first prototype of this system. This system implements an attraction particle system beetween a vector wich points to a finger position (Leap Motion) and other vector (pendulum). I’m using firmata to create an interface between arduino boards wich controls the position of the servo motors and a software developed in Processing. This software recives leapmotions’s signal and interprets as an specific position for every motor, this system allows to create an interactive experience. I’m planning participate in Transitio MX 2017 (http://transitiomx.net/) with this interactive installation.
