Meanders.
The angle of the direction of the flow at any point is proportional
to the sine of the total channel distance up to that point.
Write up that statement in code and you'll draw meanders on your screen.
Start with a proportionality constant of 0.1 and go from there.

Convex when it bends outwards, concave when it bends inwards
