  A rising number of HCI scholars have begun to use materiality as a starting
point for exploring the design's potential and restrictions. Despite the
theoretical flourishing, the practical design process and instruction for
beginner practitioners are still in scarcity. We leveraged the pictorial format
to illustrate our crafting process of Puffy, a bio-inspired artifact that
features a cilia-mimetic surface expressing anthropomorphic qualities through
shape changes. Our approach consists of three key activities (i.e., analysis,
synthesis, and detailing) interlaced recursively throughout the journey. Using
this approach, we analyzed different input sources, synthesized peers'
critiques and self-reflection, and detailed the designed experience with
iterative prototypes. Building on a reflective analysis of our approach, we
concluded with a set of practical implications and design recommendations to
inform other practitioners to initiate their investigations in interactive
materiality.
