Two strangers in a shopping mall who share something in common are selected to subtly control the patterns in the mall's ceiling and floor through their movements. Their control of the environment is meant to create curiosity and lead them to discover each other. When they collide, the environment makes a colliding pattern and resets to default. The idea is to bring common people together in a public space.

3. The Idea

4. What? A responsive space that is controlled by two strangers in the crowd who share in something in common.

5. What? Two people are identified among the crowd who have something in common. These two people(or sets of people) then become controllers of the environment. Their movement controls the patterns of the ceiling and floor. The participating individuals subtly realise they are changing the space and this creates emotion of curiosity and delight. They may be led to figure out who the other person is and upon colliding the environment makes a colliding pattern and collapses to the default state. The other public is also engaged in noticing the changing environment by the controllers. The idea is to pick up common people and bring them together in public.
