Isee in the window of Konditor and Cook, the upmarket patisserie in London's fashionable Waterloo district, a tempting facsimile of the Millennium Dome. Chocolate substitutes for the fabric, and plastic spoons for the masts, but its description is even more enticing. 'Mind zone . . . it's witty; spirit zone . . . it's good to eat; communication zone . . . share it with others; transaction zone . . . cheaper than the real thing.' No kidding.
