An apparatus for assisting people with walking wherein those apparatus are reconfigurable to provide seating in either the forward-facing, or the rear-facing direction, includes a foldable, wheeled frame assembly, a seat mounted to the frame, and a reversible cross-arm, or backrest, for reconfiguring the apparatus from a rear-facing seating arrangement to a forward-facing seating arrangement. In a further aspect, hinged arms, one on each side of the frame assembly, are operable to at least partially rotate in a plane adjacent to the plane of the frame to which it is attached, thereby offering alternative positions of the arms that are convenient to the forward-facing seating position and the rear-facing seating position.

Selected patterns of lights are displayed on a recreational conveyance such as a snowboard according to the motion of the board. A selection of patterns is stored in a processor memory, the motion of the board is measured (for example with accelerometers) and a pattern is selected from memory based on the measured motion. Then lights on the board are blinked on and off in the selected pattern. Accelerometer inputs are analyzed and a series of states is derived for each accelerometer axis. A series of states can be analyzed as a set to select a different pattern. Also, the magnitude of the states (such as duration, speed, or intensity) may affect the pattern selected. The process may be adaptive, so that the analyzing step further analyzes user weight or past snowboarding style to set adaptive thresholds for selecting patterns.
