A wheeled toy adapted to respond interactively to movement comprises sensor means adapted to detect a change in movement selected from speed, direction and angle of orientation, computer processing means adapted to process signals from the sensor means, to calculate the orientation of the toy, and to generate an electronic response, selected from a series of pre-selected responses, appropriate to said orientation or change in movement, communication means adapted to receive said electronic response and to generate a visual or audible response which can be sensed by a user of the toy in order to prompt a change in said orientation or movement.
