The standing ovoids of light are autonomous. Ovoids also float freely in the air and stand autonomously across the ceiling.

When an ovoid is pushed by a person and tips over, the color of its light changes and a tone specific to that color resonates out. The surrounding ovoids respond one by one, continuously changing to the same color and emitting the same tone.

Typhoon light balls float between the floor and the ceiling within the confines of the space, as though transcending the concept of mass. When a person touches a typhoon light ball, its color changes, and it emits a sound tone unique to that color. One after another, the surrounding balls successively change to the same color and emit the same tone.

Because the typhoon light ball and ovoid colors are produced by light, it is possible to create 9 blurred colors (light in water, sunlight on water plants, morning glow, morning sky, sky at twilight, peach, plum, iris, and spring maple), as well as 3 base colors (blue, red, and green), producing a total of 12 colors.
