Sustainability in HCI is a growing area of research, and a driver of creativity for developing new and interesting interfaces. Low-power technology such as e-ink or flip-dot displays have provided some alternatives, and living media displays present a new opportunity to study displays that consume low amounts of energy. This pilot study explores the design space for a moss-based dispaly installed in a design school, through think-aloud, observation and interview with 10 participants. The study found that users enjoyed the novelty, appearance and interaction with the moss display, showing promise for future applications. We contribute three design considerations and potential applications based on these findings.
