This is a series from teamLabBall (2009-) featuring soft and flexible sculptures that relate to people’s bodies, sculptures that change the relationship between people and the space through the influence of people's behavior, and spatial sculptures with ambiguous boundaries.

When an Ovoid is pushed by a person, or swayed by the waves, the Ovoid falls back and then rises, releasing a resonating tone. The Ovoids around it also respond one after another, emitting color, and a sound tone that continues to resonate.

The space of the artwork is interactively transformed under the influence of the behavior of the people in the space, making the environment and the people a part of the work. This allows the artwork and people, the self and others, to continue without boundaries.

The Ovoids can change into a total of 32 newly-defined Solidified Light Colors.
