In Binary Codex: The Bar Code of Identity, I reframe my inner architecture as a grid of binary decisions—a barcode in which each column encodes a fragment of my self. The work area is subdivided into a non-overlapping grid of cells. In each cell, a random binary choice determines whether a short vertical stroke is drawn. A “1” is rendered as a vertical line centred in the cell (with slight top and bottom gaps to ensure separation), while a “0” leaves the cell blank. Each column is assigned one colour (chosen from a restricted nine‑colour palette) that marks its entire sequence. Together, the discrete marks form a visual codex that symbolizes how individual data points combine to create a coherent, modular self.
