Looking for an opinion

I am a novice at grasshopper and wanted to know if anyone had any ideas that could improve my definition.

I am trying to use proxemic relationships between people to make an installation that would encourage social interaction.  The information would then relate to an inflatable device that would regulate its volume based on those conditions.

My model currently shows the radius (the individual's proxemic setting) around the person and a corresponding cell of the voronoi above.  Right now I have to change each individual's radius and their location. 

Is there a way to be able to have all of the "people" rearrange by moving one "person's" location and/or proxemic setting?
