Generate random curved circular shaped voids in a square

Question

Can you help me to generate randomly distributed void curved circular shaped voids in a square. the figure below shows an example.

Answer 1

I would call this solution experimental, but it may help you:

The principle behind it is relatively simple, and there are a lot of possibilities to influence the result individually.

1. First I create a grid and move the single points. The node Map Range helps me to clamp values. With the node Merge by Distance I bring further disorder into the structure. Finally, I split the faces so that they can be edited separately:

   

2. In the next step I move the vertices a bit into the center of each face. To do this, I convert the faces into curves, divide them once, and then select every other point to move it with a slight random value:

   

3. Finally, I resample the curve to get a higher resolution and apply the node Blur Attribute, which smooths the positions of each curve point for me:

   

4. Finally, I combine the result with a qudratic shape (Quadrilateral), which in this case acts as an outer frame, and Fill Curve creates the desired mesh:
