Ernő Rubik's Magic Cube from Budapest, a worldwide obsession by the early 80s. This is a 1980 cube as Ideal Toy sold it, made in Hungary and still wearing the gold seal from its pack, rebuilt from photos of real ones down to its original colour scheme - the mirror image of today's (turn your sound on). Drag any row or column to turn it, the middle ones included; drag beside the cube to look round it. On a computer, U, D, L, R, F and B turn the faces as cubers write them, M, E and S turn the middle slices, and Shift turns them the other way. Like a real cube, it stays as you leave it.
