CURATORIAL TREATISE

From Physical Lineage to Digital Space

“The bronze remembers the hand that poured it; the city is arranged in fractal circles mirroring the village and the cosmos.”

The historic City of Benin was engineered using mathematical fractals: the royal palace at the center radiated into nested recursive courtyards and modular urban neighborhoods with mathematical scaling. This extraordinary African urban planning tradition directly informs modern fractal UI layouts, nested CSS subgrids, and component hierarchy trees.
