[1][2] Coelho makes objects, installations, and live experiences that challenges people's perception of material properties and behaviors.

Six-Forty by Four-Eighty, a 2010 installation by Coelho, uses interactive physical pixels and body communication to convey an immersive digital graffiti experience.
