Built in 1607, Fukuoka Castle is also known as the Stone Castle. This installation artwork makes use of the stone walls of the great castle tower ruins. 

Yatagarasu (three-legged crows from Japanese mythology) are rendered in light, as they fly around the space, they leave trails of light in their paths and create spatial calligraphy. The crows chase one another and in turn become chased themselves. When the chased crows crash into one another, they scatter, turning into flowers. 

The light that draws the crows is black, meaning there is no light, thus making it indistinguishable from the shadows of the stone walls that have been weathered over the past several hundred years. The crows merge with the shadows of the stone wall as they fly.
