Demaray concocted a lichen slurry consisting of lichen with natural protean substrate that was spread on various surfaces of buildings after gaining permission from the owners. It takes about three months for the lichen to propagate. If it doesn't take, it simply dries up and blows away to find another place with more favorable conditions. A video of the plantings and walking tour are currently being produced featuring time-laps footage.
