Ecocidal Graffiti:  Urban microbial ecologies are easily overlooked. Microgeography is not afraid to partially and temporarily destroy such ecologies if it results in their revelation, and if in the process, city dwellers are jolted  off their predictable macroscopic paths. Ecocidal  Graffiti is a novel microgeographical technique which differentially destroys parts of microbial communities in situ so that images, glyphs or text are created within them and as a result,  the ecologies themselves become highlighted by their own absence. The initial application is invisible but as the treated parts die, the images or text mysteriously appear over a period of 1-5 days. These are tests for the process which clearly show its efficacy. Please comment should you be interested in joining me on a national campaign of Ecocidal Graffiti.
