A system includes a light-emitting diode (LED) circuit comprising a set of LEDs arranged in a formation, wherein the set of LEDs comprise a set of LED clusters; and a controller. The controller is configured to: control, according to a first LED control mode, whether each LED of the set of LEDs is turned on or turned off; and control, according to a second LED control mode, whether each LED cluster of the set of LED clusters is turned on or turned off, wherein the first LED control mode requires the controller to use a first amount of computing resources, wherein the second LED control mode requires the controller to use a second amount of computing resources, and wherein the second amount of computing resources is lower than the first amount of computing resources.
