Cumos Cube

An eye-popping optical toy that recreates the "cosmic conception" within a small cube.


Minori Yamazaki

Space production designer and modeling artist. Mr. Yamazaki began with the palm-sized peeping box CUMOS, which he devised when he was a freshman at Tokyo University of the Arts, and has been involved in light art, space production design, display design, art installation, etc. for cosmic infinite reflection images. He pursues modeling with a fundamental image in a simple structural feeling.

Origin Japan
Dimensions 3.5 x 3.5 Inches
Material Acrylic

Traditional kaleidoscopes create a two-dimensional image while CUMOS conjures a mesmerizing three-dimensional space. Peek inside the cube to discover a psychedelic world that seems to flirt with the edge of infinity. Intricate geometric patterns offer new details upon each viewing.

As if that weren't fascinating enough, when you move the included LED light around the outside of the cube, you can watch the universe inside change colors! Designer Minori Yamazaki says CUMOS was inspired by the cosmic conception. His groundbreaking optical toy is certainly awe-inspiring.

Each Cube is carefully constructed by the artist and then signed and dated for authenticity.

Please note: The Cosmos and Rhombus Cubes are considerably more expensive because they are slightly larger and the mirror arrangement inside is three times more complex. The Universe Cubes come in a variety of interior styles and will be sent at random.
