This artwork starts when the crows leave their exhibition spaces.
The crows cross the boundaries of other works, and fly around freely as they influence the artwork spaces that they enter. For example, the crows fly and scatter flowers in other works, or in the case of What a Loving, and Beautiful World, if the crows fly into a Chinese character, the world contained within that character will appear.

Flocks of mythical crows (Yatagarasu) rendered in ink fly around the space leaving trails in their wake and forming Spatial Calligraphy. The chasing crows are eventually chased themselves, and form flowers when they crash into each other, scattering their petals. Although the crows usually avoid crashing into people in the space, when they happen to do so, they similarly form flowers, their petals scattering.
 
The artwork is not a pre-recorded image that is played back; it is created by a computer program that continuously renders the work in real time. The interaction between people and the installation causes continuous change in the artwork, so previous visual states can never be replicated, and will never reoccur. The picture at this moment can never be seen again.
