Nox Nox is a nocturnal stuffed animal, afraid of daylight and only comfortable in the darkness. Nox quietly purrs in the dark but gives a theremin-like squeal that increases in pitch as she approaches a light source. I wanted to design a companion for children afraid of the dark. I felt that a toy with an opposite attitude towards light and darkness would not only counteract that fear, but also encourage them to consider those whose needs and preferences run counter to their own. Using Arduino, photoresistor, code, fabric, sewing machine. Nox website.
