On the series of grey images, there is the amoeba Dictyostelium, which comes together when one is starving to create a multicellular organism that transforms first into a slug-like creature, then a tulip-like stem and bulb, eventually sporing onto an insect which brings the amoebae to a place with more food. In the other series, there are images of oats placed in the same layout as Japan's largest cities. Slime mould consumes the oats, finding the most efficient route between oat deposits, effectively mirroring the paths of the railway in Japan.
