The space is filled with ovoids of light. People move through the ovoids and enter the space.

People recognize the multi-dimensionality of the space when the group of ovoids shine with various blurred colors, but the space feels flat when the ovoids are monochromatic. As the space changes between three dimensions and two dimensions, the whole body is immersed in both a three dimensional space and a flat plane. 

When people strike the ovoids of light, it causes the color of the ovoid to change, and a tone specific to that color resonates out. The surrounding ovoids will respond, and the same color and tone will resonate radially throughout the space.

Each ovoid moves freely, but no matter where it is, the behavior of light is maintained across the entirety of the space. Therefore, the light behaves as a group and can be thought of as one three-dimensional existence. The light resonates out spherically across the space from the impacted ovoid. While recognizing the light’s three dimensional existence, people push through the ovoids to enter into that existence.

Since the 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 colors that flatten the space (blue, red, and green), resulting in a total of twelve colors.
