A server stores image data in a storage device and transmits the image data to the rotating displays. The storage device stores user data. user data includes a type of each rotating display held by the user. The user data includes a time schedule for displaying the image data. The server supplies to the terminal device an operation screen for user interface. User interface allows to select the image data and a time schedule for displaying the image data, or allows the user to create displayable image data. The server has a display controller that transmit to the rotating displays the image data, that selected or created by the user and transmit the data indicating the time schedule.

A display method for a wheel rotation imaging device includes: acquiring operation information, the operation information comprising ambient light intensity, wheel speed, vehicle acceleration, current time, current location, and current power; identifying a situational mode of vehicle driving according to the operation information, the situational mode being in one-to-one correspondence with a power consumption mode; and selecting a power consumption mode of the wheel rotation imaging device according to the situational mode, so that the wheel rotation imaging device completes display according to the power consumption mode. The wheel rotation imaging device is mounted on a wheel and can display texts, images or videos as the wheel rotates.

Examples of creating moving light patterns in a light pipe having a plurality of Light Emitting Diodes (LEDs) are described. In an example, a plurality of keyframes is obtained. The plurality of keyframes define the moving light pattern. Each keyframe is indicative of red-greenblue (RGB) illumination values of each LED 5 from the plurality of LEDs. Further, a linear interpolation is performed, at run-time, between two keyframes of the plurality of keyframes to obtain a plurality of interpolated frames. Each interpolated frame is indicative of interpolated RGB illumination values of each LED. Based on the RGB illumination values of 10 the plurality of keyframes and interpolated RGB illumination values of the plurality of interpolated frames, the plurality of LEDs is illuminated, to create the moving light pattern.
