The self-righting ovoid objects are autonomous, they shine brightly and then fade as if they are slowly breathing.

When the objects are pushed by people, the color of their light changes, and they emit a unique sound tone. The color and the sound then resonates out to the objects around them. The resonating light is transmitted to the next object one after another, spreading the color tone in the same way continuously.

If a wave of light rushes from one direction, it signifies the presence of a person in that location. As a result, people gain a heightened awareness of the presence of other people in the same space.
