Hopscotch: A Game of Borders

TerritoryComputationalParticipatoryPlay

A Game of Borders begins with a familiar childhood game and a question. How are worldviews and border logic embedded in the games of childhood, and what might it mean to play them otherwise?

The traditional hopscotch game contains in its grid a miniature system of territories, permissions, constraints, and movement. Each square is a delimited territory, while its lines function as limits with conditional crossing. There are spaces a player may temporarily occupy, spaces they cannot enter, and prescribed ways of moving between them. Usually, one person advances while another waits.

The installation changes this familiar structure. A hopscotch grid, composed of fading red lights, is approached by two participants from opposite ends. A webcam tracks their positions as they move square by square toward one another. The closer they get, the more intense the surrounding sound becomes. Eventually, they meet in the same grid, where each person’s path is occupied by the other and the traditional rules stop providing answers.

To continue, the players must decide what happens next. They may negotiate, adapt, cooperate, improvise, step aside, or invent new rules. Because there is no programmed solution, each encounter unfolds differently: some participants hesitate, some collaborate immediately, and others begin to laugh.

Rather than telling people how to think about borders, the work makes questions of territory, coexistence, and movement physical. The audience activates shared space, crosses conditional boundaries, and rehearses new ways of being together. The installation becomes complete only when people step into it and play, transforming the shared space into something of their own.

Process

The installation combines an illuminated LED grid, webcam body tracking, p5.js, ml5.js, Arduino, and responsive sound.

The system tracks the distance between the two participants. Their relationship in space becomes one of the main inputs controlling the installation.
