Indian muralist Priya Kapoor has pioneered "The Wall as Classroom" initiative, converting Mumbai's slum walls into interactive educational murals. Her project combines UV-reactive paints with QR codes that link to audio lessons on sanitation and nutrition, activated by smartphone flashlights.

Kapoor's signature style blends Rajasthani miniature painting with graffiti techniques, featuring modular panels that residents can repaint using provided eco-friendly pigments. Each mural includes rainwater harvesting channels disguised as artistic flourishes, addressing local water scarcity issues.

The initiative has transformed 32 public walls into learning hubs, with UNESCO funding expansion to Nairobi's informal settlements. Kapoor's workshops train women to maintain the murals, generating income while preserving artistic integrity.

"This is art serving humanity," Kapoor stated. Her work has inspired Brazil's favela beautification programs, while her UV-pigment technology is being tested for highway safety markings in Sweden.
