School plays an essential role in cultivating community atmosphere, especially for the next generation. Moreover, it is beneficial for students to root deeply into their local community, creating more coherent ties between family life and school. To promote interactions between community and school, I hope to turn the courtyard from a solid bar into a series of spaces, encouraging students and community members to get involved in several programs. Hence, the entity boundary is transformed into a soft and kinetic boundary. The form obeys the rule resulting from kinetic analysis of a game called freeze tag, which is one of the most popular games in my childhood memory. By paralleling the teacher to the chasing one and the student to the chased one, I got the prototype of form.
