Sorry, I meant firing "up" the DISH.
DISH stands for Digital Immersive Showroom. It's a room/system at Imagineering in Glendale and their office in WDW at Epcot to ride through attractions, experience a land virtually, and examine any sightline problems, among other things. Here's a video of a ride through in the room of the Incredicoaster and walk-through of TSL.
