Make it dynamic: let each cell get the average value of it's neighbor

[aptoptout]

Idea to make it dynamic: Start with the original force field, then in each iteration make each cell get the average value of it’s neighbors, will it arrive to a stable state, will it run for ever? Statistical physics of books!

See: Potts model - https://en.wikipedia.org/wiki/Potts_model & XY model - https://en.wikipedia.org/wiki/Classical_XY_model.

@davidpb90 We need to discuss this, I'd love to start implementing this and I want to understand it but I need your help with especially the latter.
