Particles is an “illumination installation” by Japanese artists, Daito Manabe and Motoi Ishibashi, which presents:

...seemingly floating lights that create a fantastic afterimage, this work centers around an organically spiral-shaped rail construction on which a number of balls with built-in LEDs are rolling while blinking in different time intervals, resulting in spatial drawings of light particles in all kinds of shapes. The illumination’s three-dimensional design, achieved through a fusion of the rail construct’s characteristic features and communication control technology, takes on various appearances depending on the viewer’s position. Look forward to an exciting new work that combines generally entertaining ideas and sophisticated information technology in everything from LED devices and other hardware to programming.

Particles is currently on display at the Yamaguchi Center for Arts and Media, Japan.
