The 3D launcher was a special effect in the all apps screen that lasted for several releases. The user saw a normal 2D grid of applications, but as they scrolled the list up and down, the top and bottom edges faded away into the distance like a Star Wars intro-text effect. It was subtle but powerful, hinting at the 3D power behind the system (and the potentially large number of apps on the system), but without being too ostentatious or difficult to navigate.
