TO get to the front door of the Elias family, the inhabitants of the new Dream Home at Disneyland
, you must step onto a revolving walkway and glide past Tom Morrow, a Nathan Lane
-voiced robot with a face like a machine-age Arcimboldo and a brush cut of stiff copper-colored wire. Tom’s body is an exposed skeleton of hydraulics, wires and transistors, and his one concession to modesty, a clear plastic lab coat, adds an unwittingly pornographic grace note. His signature song, “There’s a Great Big World of Innoventions” — audible no matter where in the home you may venture — will play dozens of times during your stay, and will run through your head with a Manchurian Candidate tenacity long after you leave.
