An Infinity cube made of dice being played with An animation showing different moves and states of the Infinity cube (click to animate) An Infinity cube is a kind of mechanical puzzle toy with mathematical principles. Its shape is similar to a 2×2 Rubik's cube. It can be opened and put back together from different directions, thus creating a ...
Cut a diagonal X across the entire center square, pinwheel-fold the outer edges, and fold the protruding pinwheel flaps inward, interleaving them to produce a multilayered square with the top woven together. Fold outward the triangular flaps cut from the center square. This creates one face of the cube; the entire cube requires six identical ...
By concatenating one of the numbers 0, 1, 2, or 3 to the chain's name, depending on whether the number of tiles to the right of the middle tile before the folding edge, a categorization of the rectangle forms is obtained. The starting position, for example, is rectangle form OUR2. The cube now is rainbow and has silver rings.
Folding a Sonobe module (1–10) and assembly into a pyramid (11–12); * denote tabs and # denote pockets [10] Each individual unit is folded from a square sheet of paper, of which only one face is visible in the finished module; many ornamented variants of the plain Sonobe unit that expose both sides of the paper have been designed.
All 11 unfoldings of the cube. A polyhedral net for the cube is necessarily a hexomino, with 11 hexominoes (shown at right) actually being nets. They appear on the right, again coloured according to their symmetry groups. A polyhedral net for the cube cannot contain the O-tetromino, nor the I-pentomino, the U-pentomino, or the V-pentomino.
Martin Gardner included this fold, described as both a bug catcher and fortune-teller, in a column in Hugard's Magic Monthly, titled "Encyclopedia of Impromptu Magic", in the 1950s. [22] Although the phrase "cootie catcher" has been used with other meanings in the U.S. for much longer, [ 23 ] the use of the phrase for paper cootie catchers in ...
Kawasaki was the first to develop the technique of iso-area folding, which allows the folder to end up with each side of the paper displayed in equal amounts. It consists of building a mirror-symmetrical crease pattern and then collapsing it to find a finished form, usually a geometric shape such as a cube.
The Yoshimoto Cube is a polyhedral mechanical puzzle toy invented [1] in 1971 by Naoki Yoshimoto (吉本直貴, Yoshimoto Naoki), who discovered that two stellated rhombic dodecahedra could be pieced together into a cube when he was finding different ways he could split a cube equally in half. Yoshimoto first introduced his cube in 1972 at a ...
