CURATORIAL TREATISE

From Physical Lineage to Digital Space

“Architecture should belong to its site; space is the breath of art.”

Frank Lloyd Wright’s Prairie School integrated horizontal shelter with the raw landscape, dissolving interior partitions into continuous flowing space. This American architectural lineage, carried forward by the Eames Office and Silicon Valley ergonomics, established the modern GUI desktop, direct-manipulation gestures, and dynamic layout scaling.
