"Duo" by Invader is a striking mosaic work composed of ceramic tiles arranged on board, showcasing the street artist's signature style rooted in the pixelated aesthetic of early arcade video games. The piece features two distinct figures or forms rendered in a grid-like pattern, with each tile functioning as a single "pixel" to create a bold, graphic image. Invader's meticulous tile-work bridges the worlds of urban street art and fine art, transforming a humble, utilitarian material into a vibrant and nostalgic composition.
