Minus design

The Minus Cube is a 3D mechanical variant of the n-puzzle, which was manufactured in the Soviet Union.
It consists of a bonded transparent plastic box containing seven small cubes, each glued together from two U-shape parts: one white and one coloured.
The length of one side of the interior of the box is slightly more than twice the length of the side of a small cube.
There is an empty space for one small cube inside the box, and the small cubes are moveable inside the box by tilting the box, causing a cube to fall into the space.
The goal of the puzzle is to shuffle the cubes in such a way that on each side of the box, all of the faces of the small cubes have the same color.

The Minus World is a glitched level found in the 1985 video game Super Mario Bros. It can be encountered by maneuvering the protagonist, Mario, in a particular way to trick the game into sending him to the wrong area.
Players who enter this area are greeted with an endless, looping water level in the original Famicom/NES cartridge versions, while the version released for the Famicom Disk System sends them to a sequence of three different levels; this difference is due to the data being arranged in different ways between the two versions.
It gained exposure in part thanks to the magazine Nintendo Power discussing how the glitch is encountered. Super Mario Bros. creator Shigeru Miyamoto denied that the addition of the Minus World was intentional, though he later commented that the fact that it does not crash the game could make it count as a game feature.

In audio engineering, a mix-minus or clean feed is a particular setup of a mixing console or matrix mixer, such that an output of the mixer contains everything except a designated input.
Mix-minus is often used to prevent echoes or feedback in broadcast or sound reinforcement systems.

The Junkie and the Juicehead Minus Me is the 48th album by country singer Johnny Cash, released in 1974 on Columbia Records.
Although credited to Cash alone, the album includes solo performances by his daughter Rosanne Cash, and stepdaughters Rosie Nix Adams and Carlene Carter, predating the launch of their own solo careers.
Two songs on the album were written by Kris Kristofferson, while Don't Take Your Guns to Town is a re-recording of a highly successful Cash single, his first smash hit for Columbia from back in 1958. Father and Daughter is a cover version of a well-known Cat Stevens song and a duet with Cash's stepdaughter, Rosie Nix Adams, with slight changes in lyrics; a version of the same song would be released in 2003 on Unearthed, as a duet with Fiona Apple.
June Carter Cash also performs a solo track without her husband, one of only a couple of occasions where she did this on a Johnny Cash album outside of concert recordings.
