The Spatial Calligraphy of the display artwork Reversible Rotation: Emptiness Black transcends the boundaries of the display and with one brush stroke crosses the boundaries of other artworks, and then goes on to continue to influence other artworks.

The Spatial Calligraphy in this artwork space rotates in the same direction, but because of the characteristics of Ultrasubjective Space, visually, the clockwise and counterclockwise rotation are equivalent. Hence, the work can appear to be rotating in either direction depending on how the viewer chooses to see it.

Spatial Calligraphy is a form of calligraphy drawn in space that teamLab has been exploring since it was founded. The artwork reconstructs calligraphy in three-dimensional space to express the depth, speed, and power of the brush stroke, and that calligraphy is then flattened using what teamLab terms Ultrasubjective Space. The calligraphy shifts between two and three dimensions.
