I like the image of a termite in Africa helping to build an elaborate nest which includes air-conditioning - without architect, foreman or drawings. Or the fact that, while my eyeballs are dragged around by five muscles each, one of these (each) has managed to pass through a hole in my skull and change direction so that the hole functions as a pulley.
