Abstract: A case for a mobile device, including first, second, third, and fourth sides, each with inside and outside surfaces opposite to each other. The inside surfaces of the first and second sides face each other. The inside surface of the third and fourth sides faces each other. The first and second sides are arranged between the third and fourth sides, and the third and fourth sides are arranged between the first and second sides, so that the four sides form at least part of a frame configured to surround a periphery of the mobile device. At least one of the inside surfaces of the first, second, third, and fourth sides includes triangular protrusions that have a triangular cross section and extend toward the inside of the case, so that an apex of each of the triangular protrusions contacts the mobile device when it is arranged inside the case.

Abstract: A recorded race is downloaded from an online gaming service. The recorded race is associated with a game program. The game program is launched on a game console. The recorded race is applied to the game program executing on the game console such that the recorded race controls a first vehicle moving through a course. Control inputs are received from an input device coupled to the game console. The control inputs control a second vehicle moving through the course.
