Red and black, antennae waving

I am more or less fascinated by these ants who count their steps to find their way home. It's just that we use such a massive amount of cognitive overhead for any kind of counting -- with our numeric symbol sets, and language acquisition, and so on -- and here these ants are counting perfectly well (and more accurately than us most of the time, I presume) by just using some kind of ticker.

That, and the whole concept of putting tiny stilts on the ants to screw up their stride lengths.
