GEO If you look closely you'll find they're actually very still. Lines are stubborn things to pin down, so you don't; you string them up. And while they insist on following a 'linear' track, it's also very easy to fool them into bending a bit here and there in a hegemonic sort of oscillation. They tend to appreciate that; they're sick of being shortcuts all the time, what with the whole "the fastest route to get from A to B" theory applied to almost everything that needs a line or two. They'll move only when you coax them, to form grids, blueprints, objects, the world.
