Moss graffiti,
also called eco-graffiti or green graffiti, replaces spray paint,
paint-markers or other such toxic chemicals and paints with a paintbrush
and a moss "paint" that can grow on its own. As people become more
eco-friendly and environmentally aware, the idea of making living,
breathing graffiti has become a more green and creative outlet for
graffiti artists. It can also be considered another form of guerrilla
gardening.

Add the buttermilk/yogurt, water/beer and sugar.
Add the buttermilk/yogurt, water/beer and sugar.
Blend the mixture until completely smooth. You'll want it to have a paint-like texture.
If the mixture is at a consistency where you feel it will drip, add corn syrup until the consistency you desire is reached.
Use a paintbrush to apply the moss-paint to the surface on which you wish your design to grow.
