The rock mass leaves the space, floats through the hallway, and sinks into the wall. The rock mass transcends the physical space of the museum itself, the sunken part appearing in a wall somewhere else in the world.

When people touch the rock mass sunk into the wall, it shines with a red light. The light travels to the rock mass protruding in other places. When people in another location touch the rock mass jutting out from the wall, it glows with a blue light, and this light flows into the remaining rock mass. When the blue light flows from the sunken part of the rock mass, it indicates that somewhere in the world, someone is touching the sunken portion of the rock mass.
