Create a pattern like bubbles with 120 degree angles connections

[s.wac]

That’s interesting. I didn’t realize that soap bubbles junctions are always 120 degree.

Here is similar pattern obtained by relaxed voronoi diagrams.

Voronoi Bubbles

If you’d like to achieve a more closer look like the water cube, by using relaxed voronoi, then, have a try “Voronax” plug-in. [Canvas at 16;11;23]Voronax_Bubbles_re.gh (23.9 KB)
