Moroccan material scientist Leila El Mansouri earned double Cannes Lions for "Solar Loom," deploying thermal-reactive tapestries across Jemaa el-Fna marketplace. Partnering with Atlas Mountain Cooperatives, the installation suspends 2,400 sqm of hemp fabric coated with thermochromic hydrogel – temperatures exceeding 38°C trigger crystalline expansion forming shaded geometric perforations. 

Embedded phase-change capsules release jasmine scent during peak heat while reducing ambient temperatures by 11°C verified by meteorological instruments. Vendors activate "cooling surges" by pouring mint tea onto copper collector plates, instantly enlarging shade patterns via capillary action. UNESCO reports show 300% longer marketplace activity during heatwaves, with textile co-ops tripling artisan income. Dubai Gold Souk now implements the technology with palm-frond composites for desert climate adaptation.
