A system and method of creating a decorative panel enables the creation of a decorative panel through a unique arrangement of illuminating blocks. The blocks are arranged to form a decorative panel. The blocks have an internal channel that contains light emitting diodes and a central conductive member. The diodes can be adjusted and removed to achieve a desired pattern or message without removing any of the blocks. The diodes and central conductive member are easily accessible from one side of the blocks by sliding them in and out for interchanging diodes or maintenance of the wires. The decorative effect on the panel may be constantly regenerated by interchanging diodes from within individual blocks, without having to move the block. This is possible because the diodes are disposed internally in the blocks. Thus, the illuminating effect from within each block is manipulated to create a desired decorative effect.
