Happy Cube
Happy Cubes are a set of mechanical puzzles created in 1986 by the Belgian toy inventor Dirk Laureyssens. The company "Happy bvba" has the exclusive license to manufacture and sell these puzzles .Happy Cubes are also known by a number of other names, among them: "Cube It!" cubes, "Wirrel Warrel" (in Holland), "I.Q.ubes" and "Cococrash" (in Spain and Portugal).
The Happy Cubes were made of 8mm-thick ethylene-vinyl acetate foam mats (also known as EVA). The tiles were based upon a 5x5 matrix where the outer squares may be present or absent. The central 3x3 kernel was fixed. Initially the puzzle is assembled into a 2-dimensional, flat 2x3 piece rectangle fitted into a frame. The basic challenge is to construct a perfect, 6-sided cube out of these 6 pieces. Usually, there is only one way to fit the pieces into a complete cube and it can be reached with various levels of difficulty by trial and error.

Famous quotes containing the word happy:
“A happy marriage perhaps represents the ideal of human relationship—a setting in which each partner, while acknowledging the need of the other, feels free to be what he or she by nature is: a relationship in which instinct as well as intellect can find expression; in which giving and taking are equal; in which each accepts the other, and I confronts Thou.”
—Anthony Storr (b. 1920)
