This is an attempt to create a hexagon pattern on a trimmed surface via Kangaroo. It looks like it was pretty successful when applying physics to layout the hexagon pattern. Maybe a further step should be advanced to dynamically add/remove the particles during the simulation process... 

I have previously seen an similar pattern done with processing from a student and remember vaguely how it can done in Grasshopper with Kangaroo. This is an experiment with the same idea. Sorry for the references, I cannot remember where did I first see these examples. Just try to mimic this pattern by myself here. I think this pattern can be easily applied onto a surface domain. Maybe I should try to apply this to one surface after today's class.

This is an exercise done last year. An attractor was used to create a trimmed pattern on a surface, coupled with an extrusion tube toward the attractor.

This is an attempt the change the subdivision grid on a given surface domain by introducing a single, or multiple, attractor(s).
