In this paper we present the Nebula, a garment that translates intentional gestures and implicit interaction into sound. Nebula is a studded cloak made from a heavy fabric that envelopes the wearer with pendulous folds and has strong experiential qualities that were especially appreciated by performing artists. We describe the design process in detail, and highlight three material investigations that show material connections that were fundamental to the experience of the garment: How the draping and construction of the garment allowed for implicit interaction, how the studs were used both as a computational sensing material and a strong visual component, and how the sound design exploited tangible material qualities in the garment. We offer these three material investigations as contributions and discuss how material investigations more broadly can produce evocative connections in the materials available in design work, but also as a way to extract legible design intentions for other designers and researchers.
