More playing about with camouflage. Alan Turing wrote the book on pattern formation.
One of his conclusions, from theorising about reaction-diffusion chemistry, was that small body parts were more likely to have stripes and larger body parts to bear spots.
Today’s invention therefore is to create a camouflage pattern which inverts this logic (eg for hunters to wear). Such an outfit would have spotted ankles, neck and forearms and increasingly stripy patterns towards the middle of the body.
The idea is that if game animals are naturally attuned to a particular arrangement of markings, as indicative of a large predator, they will be less likely to detect the shape of a person wearing a highly atypical variant on this.
