Brussels Sprout Island is a research-creation and design-research prototype that examines how climate-friendly diet can be reframed as a sensory, relational, and non-shaming public communication practice. Rather than presenting lower-emission eating through carbon-footprint instruction, moral correction, or individual restraint, the prototype stages planting, cooking, sharing, slow environmental feedback, and repair as interaction mechanisms. Using interaction logs, pre/post micro-surveys, and short exhibition interviews with a small convenience sample (N = 16), the study asks whether participants can temporarily reframe climate-friendly eating through rhythm, care, shared meals, and repair rather than guilt or dietary purity. The findings are formative and exhibition-bound. They indicate short-term reductions in perceived judgment and guilt/shame, increased relational and self-efficacy language, and preliminary behavioral traces of kitchen/table repair routes after the monster trigger. The contribution is therefore a design-research prototype and provisional interaction grammar for future comparative and longitudinal testing of non-shaming climate-food communication.
