Triangular Tesselation - Hexigrid Randomization

Hi! I had a couple of questions that I seem to be stuck on for adding some randomization to a hexigrid script I've been working with. I'm a beginner so I have some sense of things but I'm having poor results when I'm trying to add scale adjustments to the triangles. The point attractor is great but I would like more variation like the attached picture of an image achieved through processing. Any guidance on how to add more point attractors cleanly to the script or could I use list randomization to add in? Any suggestions would be helpful on direction!  Thank you!  In short I'd like to achieve an array of triangles that could be scaled at random between 100 - 70% so i could cull some of the triangles when they get too small. 

Cheers!
