Creative Rationale

This piece captures the atmospheric conditions above the high Andes of southern Peru and northern Bolivia, where the extreme altitude creates a unique microclimate of low pressure and cold temperatures despite the tropical latitude. The exceptionally low sea-level pressure reading of 636.6 Pa with its steep gradient, combined with the cold 4.6K temperature and high humidity, inspired a composition of densely packed, obsessive dot patterns that seem to compress and expand like air molecules under atmospheric stress. The gentle 1.9 m/s wind becomes a subtle directional flow in the arrangement, while the high humidity and minimal precipitation manifest as layers of translucent, cosmic circles that pulse between deep purples and electric magentas against a stark contrasting void.
