Fantastic Hammer Tap transforms indoor environments into smart interactive spaces with two built-in games: a puzzle game in which children hit the projection wall to complete puzzles, learning to recognize colors and shapes while developing observation and analytical skills, and a Protect the Earth game in which children strike pollution bubbles falling toward Earth, building environmental awareness. These experiences make learning active, competitive, and fun while protecting children's eyes and encouraging teamwork. Client: OUTPUT Location: HKRI Taikoo Hui, Xintiandi, Shanghai
