Modularized self-addressing apparatus and method

A method performed by a control unit in an array of multiple self-addressable control units arranged in at least two dimensions, wherein one of the multiple self-addressable control units in the array is located within a first longitudinal tube of a lighting display having a first attachment extension on an outer surface thereof, and another of the multiple self-addressable control units in the array is located within a second longitudinal tube of the lighting display having a second attachment extension on an outer surface thereof, and wherein the first and second attachment extensions are configured to attach to each other, the method comprising:

• attaching the first longitudinal tube of the lighting display to the second longitudinal tube of the lighting display by connecting the first and second attachment extensions to each other;
• obtaining information to be used to determine a self-address;
• determining a self-address value based upon the information;
• storing the determined self-address value;
• based upon the self-address value, specifying first data to be provided to a next self-addressable control unit in a first group of self-addressable control units for a first dimension of the array;
• providing the first data to the next self-addressable control unit in the first group;
• based upon the self-address value, specifying second data to be provided to a different self-addressable control unit in a second group of self-addressable control units for a second dimension of the array different from the first dimension of the array;
• providing the second data to the different self-addressable control unit in the second group;
• and
• identifying when the one of the multiple self-addressable control units in the array has moved from a location within the first tube by more than a specified threshold amount and dynamically re-addressing at least the one of the multiple self-addressable control units in the array to account for the movement.
