The artwork demonstrates the transformative and generative forces at play as nature reclaims human-made structures. The piece is titled after one of many specific lichen found -   muralis -  named after the aesthetic qualities inherent to the organism's growth cycle. 
 Pigments were harvested from the island along the shoreline and the interior of the jungle. Bright red, orange, yellow, and lavendar ochres were processed from island soils. Bone black pigment, rendered from charred bovine bones - a by-product of the Brazilian cattle farming industry - supplement the earth palette. Without a binder present, the mural will slowly deteriorate as natural weather and biological systems interact with the wall surface. 
 Close inspection of the work reveals the multitude of species colonizing the wall surface. Micro-organisms feeding on organic material support more complex species in inhabiting the wall's architecture.
 The untreated wall demonstrates a wealth of organic activity.

 Yellow ochre pigments are harvested from rich clay deposits, ground, processed, and tested.
 The state of Sao Paulo is rich in iron oxide soils that are harvested for a variety of industrial purposes. 
 Ninety days after its completion, the mural demonstrates aesthetic changes likely due to weather conditions, seasonal shifts, and biological processes between the microflora and the iron-rich media used in the painting. (Image: Tamar Granovsky)
