Tet in Hoi An is a product idea inspired by Vietnam’s Lunar New Year celebration in the historic town of Hoi An. With nearly 5,000 LEGO pieces, it recreates three riverside buildings featuring warm yellow facades, festive lanterns, dragon dances, shops, café, and cozy family interiors, capturing the joyful, communal spirit of Tet. Innovation Play enhances the set with an optional AR-driven experience, where players scan the model to unlock character stories, cultural learning, and cooperative challenges, blending physical LEGO play with interactive storytelling and education.
