Check out three ways how to work with attractors. If you didn’t read the book yet, find the chapter on attractors here: http://grasshopperprimer.com/en/1-foundations/1-3/2_working-with-attractors.html
You can use native GH Vector field components from the Vector tab:
04 - Attractors - More attractors with native GH components
You can use attractors to deform a grid. Going point by point, you can change shape of every hexagon and then connect the points back together to a closed polyline:
04 - Attractors - Grid deformation with colors
Or you can use Data tree to make basic GH points work together as many attractors using Mass Multiplication or Mass addition:
04 - Attractors - More attractors with basic math and Data tree
Here’s some interesting facts about sound and other fields: The inverse square law.
