Grass Jigsaw is a part of the "LUKYANG Clinic" exhibition showcased at Bangkok Design Week 2024. This exhibition employs natural principles to heal people's minds by creating various games, such as a question-answer game to find the most suitable tree seed capsules for you and Grass Jigsaw. This exhibition is part of a series on sustainability under the LUKYANG brand. In 2023, the exhibition titled "Waste โภชนา" focused on food-related waste management through art, using recycled food packaging to create food paper crafts. For Chiang Mai Design Week, the LUKYANG Clinic exhibition presented the Grass Jigsaw game and art from tree planting capsules, allowing Chiang Mai residents to engage in activities designed for mental healing. The Grass Jigsaw concept is inspired by the need for green spaces. According to research by the World Health Organization, cities with good environmental conditions should have 9 square meters of green space per person to support mental well-being. However, due to the limited living space in urban areas, this green space was scaled down scale of 9 square meters, creating a jigsaw game for relaxation and mental healing.
