A unique feature of the murals is that they are created with air-purifying paint. In interacting with emissions  – for example, from transportation and power plants  – the paint transforms harmful particles into harmless substances that the next rainfall will simply wash away. “As we are using paint that purifies polluted air, it inspired me to paint a mural related to pollution,” comments Kerim Musanović, a 3D street artist from Višegrad, about his mural envisioning water pollution. “We are trying to create lungs for the city,” adds Benjamin, “mirroring the effect of planting a thousand trees.”
