Bacterial image of Isaac Newton photosynthetically grown on the glass surface of the bottom of a petri dish using aqueous media.
The Photosynthetic bacteria were cultivated and isolated in the artist’s studio laboratory, from winogradsky columns made up from garden samples of organic materials.
The image used was taken from the NPG’s Godrey Kneller portrait of Newton, and by using transparent acetate masks with lightboxes, the image was grown in 21 hours.

Image created as a logo for Artificial Life XI: The Eleventh International Conference on the Simulation and Synthesis of Living Systems (http://alifexi.alife.org/)

From the introduction to the Proceedings:

“We chose to promote the conference with an image that is in some sense itself an example of artificial life: a real organism artificially encouraged to adopt the shape of the host country (plus Ireland). The cover of this proceedings volume features a photograph of a single-cell creature, the slime mould Physarum polycephalum, that was grown over a period of between twelve and twenty-four hours in a petri dish. While we have tidied the image up a little, it is essentially undoctored. The slime mould was grown by Soichiro Tsuda, and photographed by Soichiro, Nic Geard and Seth Bullock. The initial idea was proposed by Richard Watson during a particularly creative lunch.

In order to achieve the shot, we used a piece of acetate with an appropriately shaped hole as a template, and grew the slime mould across this area. The network of microtubules that you can see forms spontaneously as the creature grows, and reflects the self-organised system of nutrient transport that the slime mould uses. Since Physarum does not enjoy acetate as a habitat, it is relatively easy to remove the template and leave behind the organism, which has adapted to the niche it was offered by creating a living map of the the United Kingdom (and Ireland).”

Faecal samples have been plated on chromogenic UTI-agar. The large pink colonies are E. coli, the small blue are enterococci and the clear slimy ones are Pseudomonas. The colours have been manipulated using the freeware GIMP, and then a small square of the large picture have been cut out, multiplied and re-assembled like in a kaleidoscope.
