Abstract: A modular collapsible shadowbox system for creating customizable decorative tables. The system comprises a plurality of individual units, each displaying a letter, number, symbol, or shape, which, when combined, form a desired word, phrase, expression, or design. The units may be folded for storage and transport, then assembled in any desired combination for use. The desired units may be aligned in a row with a tabletop secured thereon for use as a table. The units may be individually lit from within, backlighting the letter, number, symbol, or shape and creating a shadowbox effect. The individual units, combined with color-customizable lighting, allow a user to create a custom table with any desired message and color scheme and is thus ideal for weddings, parties, and other events.
