After tinkering a conventional servo to read its position data, I'm still figuring out a way to apply this feedback reading into an aesthetic application. Even though I'm unsure on how can I implement this into the former concept, it certainly sparks interesting interactive possibilities. The code can be found in this Github Repo.
I also started a sketch around a servo triggered by a digital input. When triggered, the servo moves across a 30º range, back and forth. The idea to explore further, is to module its speed by an analog input, and maybe add a noisy (perlin most likely) effect.
