Anya Gallaccio is a Scotish artist who currently teaches at the University of California, San Diego. The piece above is Red on Green (2012). The instillation is the life and death of 10,000 red roses. It is a simple idea but so beautiful.
"A core aspect of her work is change and transformation. Both the ephemerality and site-specificity of all her work make it notoriously difficult to document. Gallaccio is careful to discard all the material related to an installation once it has closed and resists photographic documentation; in this sense her work is anti-monumental, unconcerned with a legacy outside the memories of those who witnessed it."
