An ongoing ‘collaboration’ with an intelligent organism.

“[In] trying to understand systems that use relatively simple components to build higher-level intelligence, the slime mould may someday be seen as the equivalent of the finches and tortoises that Darwin observed on the GaIápagos Islands.”   Steven Johnson, Emergence (2001). 

Since 2008 Heather Barnett has been working with the true slime mould, Physarum polycephalum, observing and influencing its growth patterns, navigational abilities and seemingly human behaviours. Used as a model organism in diverse scientific studies, the single cell organism is attributed with a primitive form of intelligence, problem solving skills and the ability to anticipate events. It is also quite beautiful, the dendritic patterns reminiscent of forms seen at varying scales within nature, from blood vessels to tree branches, from river deltas to lightening flashes.

The organism is a nomadic information system. As it creeps across its terrain it makes continuous micro-decisions about surrounding atmospheric conditions and resource distribution. With no brain or sensory organs, this amorphous cellular mass computes the complexities of its environment through chemical signalling. It is a highly adaptive biological barometer.

Barnett’s time-lapse films, photographic studies and participatory experiments take inspiration from the vast array of research relating to the slime mould – which includes city planning, cellular computation, decision-making and learning – in a game of creative control and authorship. The Physarum Experiments is an exploration of the simple yet complex behaviours of this biological and cultural phenomenon.

Study No.026: Intraspecies Fusion

The slime mould, Physarum polycephalum, meets another of its kind…

Study No.020: protoplasmic streaming

Microscopic video of protoplasmic streaming (the central intelligence system within the supercell).

Study No.019: The Maze

The slime mould navigates a replica of the classic maze experiment by Toshiyuki Nakagaki at Hokkaido University in Japan.

Study No.016: collective experiment establishing likes and dislikes

(made at Margate Photo Festival with visitors)

Visitors to the exhibition were invited to feed the slime mould (with a variety of substances) to establish likes and dislikes. At the end of the festival the film was compiled and shared online, many people contributing to one film. Some responses are obvious (it likes oats and pasta, doesn’t like pharmaceuticals), but the response to chilli powder and tobacco is mixed – something to be tested more in future.

The Creeping Garden:

Heather is one of the key contributors featured in this documentary about slime moulds and the people who work with them.

The Creeping Garden is a feature length creative documentary exploring the work of fringe scientists, mycologists and artists, and their relationship with the extraordinary plasmodial slime mould.

Co-directed by artist film-maker Tim Grabham and writer and film curator Jasper Sharp, the film follows in the unconventional footsteps of Grabham’s previous feature ‘KanZeOn’ and Sharps fascination with the extended world of mycology.

With an original soundtrack composed by celebrated musician and producer Jim O’Rourke (Sonic Youth, Werner Herzog’s ‘Grizzly Man’) this is a unique exploration into a hitherto untapped subject matter, observing and immersing the audience into the worlds of the observers and the observed.
