Biofilms as interspecies microbe communities that communicate through quorum sensing and electron exchange, this communication allow for collaboration in a way that I  to relate to that of a tissue of cells that reproduce and work forming a waved tissue, a living structure.  I want to look at them as a surface, as a living texture, as an ecosystem. Living material that in some cases like with kombucha scoby, leaves a cellulose carcass behind or like with stromatolites, after thousands of years leaves a fossilized structure. But most biofilms, are ephemeral. They carry out normal life cycles as a community responding to the media they film lives like an organism, like tissue comprised of millions of unicellular organisms organized.
