HowStuffWorks has up an article describing how the Nintendo Amusement Park works. This is the New York city area theme park in the making with a physically augmented ride themed around Super Mario Bros. They plan to make the side-scrolling course 100 meters long with a safe and fully interactive course with foam crash padding platforms powered by hydraulic actuators."
From the article:
"It's really a single 'ride' — a real-life interactive adventure that allows players to dress up as Mario or Luigi, enter the Mushroom Kingdom and perform the actions that the heroes perform in the video game. Players can jump over obstacles, land on and ride moving platforms, and smash enemies. They can even collect gold coins and punch power-up boxes."
