Thank you to Andreas, the creator of these cubes. He is an amazing person and artist. These cubes are hand made by Andreas. A full set of four GeoCubes consists of: 144 rare-earth magnets, 144 fabric and non-fabric tape hinges. 48 pieces of heavy cardstock paper and more than 50 feet of transfer-tape. It takes Andreas around 3 hours to create a set of 4. You can purchase these cubes and other versions of them on his site:

Bathsheba - The Gyroid

 

Citation

The gyroid is a "triply periodic minimal surface" that dives all space into two congruent regions. A minimal surface is a surface for which every piece of the surface has the smallest possible area needed to span the boundary of that piece. You can find minimal surfaces in real life by dipping a wire frame into soapy water. This beautiful steel/bronze representation of the gyroid was created by Bathsheba Grossman. 1.4"L x 1.4"W x 1.4"H

Captured Gears is an irregular planetary-gears system. The triangular inner sun gear sticks though the square outer annulus gear. The seven planetary gears are captured in between and the turning creates varying compartimentization of those seven. Inspired by this video:

J'ai pas mal de flip cubes avec quelques variantes (le "cube" de Naoki Yoshimoto en est une) mais j'ai récemment acquis un modèle solide, en dur, avec des pièces mécaniques, du nom de Infinity Cube, en voici un modèle de luxe :

 

Il existe des modèle chinois à quelques euros. 

Et un modèle en papier pour presque rien :

Encore plus joli :
