This is an amazing documentary about the research computer scientists are doing on slime mold. They are using the slime mold to solve maze and networking problems and even operate robots.
In one experiment, oat flakes were placed on a dish to represent the major cities around Tokyo and the slime mold was placed in the corresponding location for Tokyo. The mold created a network between the oat flakes that was strikingly similar to Tokyo’s rail system. My complaint about the experiment was that it did not seem to take topography into consideration, but I looked into it and they used light to simulate mountains, water, and other obstacles. Neat!
