Even for nocturnal amphibians? Even for intelligent knots of
superfluid vortices in neutron stars? And just because they have
vision doesn't mean our 2D pictures mean anything to them, since they
might rely on phase information or have a movement-based visual system
like many predators on Earth.

But are grids obvious? Maybe the most obvious grid of all is a
hexagonal array (that patterns occurs very often in nature and complex
systems, while square arrays are very rare).
