mikejuk writes "You can build a computer out of all sorts of things — mechanical components, vacuum tubes, transistors, fluids and ... crabs. Researchers at Kobe University in Japan have discovered that soldier crabs have behaviors suitable for implementing simple logic and hence — with enough crabs — you can achieve a complete computer. The Soldier crab Mictyris guinotae has a swarming behavior that is just right for simple logic gates (PDF). When two crab swarms collide they fuse to make a single swarm — and this is enough to build an OR gate."
Gosh that takes me back... or is it forward? That's the trouble with
time travel, you never can tell."
