John Metcalfe was CityLab’s Bay Area bureau chief, covering climate change and the science of cities.
His latest creation is a fuzzy skull-and-crossbones in Grenoble, France.
French street artist GREEN is into all kinds of sylvan weirdness: carving a big bug from wood and sticking it on a public wall, drawing on a fungus to make it appear like a misshapen Winston Churchill. But the pseudonymous hacker’s latest pursuit might be the strangest yet.
GREEN is painting designs on walls that become living colonies of moss. The methods he’s using are unclear, though this guide to moss graffiti recommends blending together vegetation, buttermilk, and “garden gel,” applying the mixture to a wall, and spritzing every week with water. (Or, after Step 1, you could just gulp it as an interesting smoothie.)
GREEN’s latest creation is a fuzzy skull-and-crossbones in Grenoble, a motif he also executed in a communal “pirate” garden in Lyon. Props to the artist for exploring an unusual medium and ever-so-slightly adding to urban greenery.
