This video game is guaranteed to move very slowly. Kimi Spencer and Marko Manriquez created an interactive mural that uses moss to depict Space Invaders:
Moss invaders comprises a living graffiti mural and a capacitive sound installation into one piece. The moss mural is made using laser cut stencils to mold a moss milkshake concoction of our own devising. The moss paste is "painted" onto the stencils to grow directly onto the brick wall surface. The sound installation aspect takes the moss invaders into the intergalactic realm. Each moss pad is a capacitive sensor which plays 8-bit musical sounds when touched.
