The games have not yet begun, and yet The Cube remains. Stood perfectly, eerily still in the centre of the transparent hexahedron is the familiar figure of the demonstrator - the "body" as it's known - distinctly feminine in shape yet somehow androgynous in its impersonality. It - or she? - does not acknowledge your presence or appear to move in any way, as though awaiting instructions - or for the beginning of the next game.
