The lost art form of elaborate, pre-PowerPoint “multi-image shows.”

987, Acropolis Convention Center, Nice. You could almost call the conference room a cathedral, but cathedrals reach toward the heavens, and this room is wide, its horizons more worldly. This is where salespeople gather—here and in identical rooms from Las Vegas to Singapore—to press flesh and make big deals. Big rooms, big deals, big pictures.  

 Today that means 80 slide projectors, braced together in a grid behind a gargantuan wall of screens, and a sound system strong enough for a rock show. The speakers have to be loud, because the din of the projectors is unbelievable. Imagine 80 slide carousels clacking through 6,400 slides right next to your ear, like a swarm of locusts.
