How can I make a square spiral (curve) in Geometry Nodes 3.4
You can solve the task with the following setup:
Here I use a mathematical setup based purely on the index of a spline and some math nodes.
I calculate a specific position in the positive or negative ...

How do I generate a rough outline around a shape in geo nodes
something like this?
If you need to keep the concave angles, try this node setup (lower performances)
If the object you want an outline on is 3D rather than 2D you can use a node setup like this

How can I make a square spiral (curve) in Geometry Nodes 3.4
Another approach using instancing.
The spiral is composed of 'corners':
on the upper left part they are growing from 2, 4, 6 etc.
on the lower right part they are growing from 1, 3, 5 etc.
