Wouldn't your latest generation tablet be way cooler if it ran on live crabs? Thanks to Yukio-Pegio Gunji and his team at Japan’s Kobe University, the era of crab computing is upon us ... well, sort of. The scientists have exploited the natural behavior of soldier crabs to design and build logic gates - the most basic components of an analogue computer. They may not be as compact as more conventional computers, but crab computers are certainly much more fun to watch.
