Zellige
A traditional Moroccan mosaic tilework, developed from the 10th century onward, in which thousands of small, hand-chiseled, glazed terra-cotta pieces (fermata) are assembled into complex geometric patterns. Each piece functions like a single, irreducible pixel[1], making zellige a pre-digital form of pixel art predating computers by roughly a millennium.
