Is it possible?

Hey GH community, is it possible to get a thread going to share definitions of different grid techniques people are using, mainly point and line type grids in grasshopper only, without custom scripts. Like ways to get hexagrids, diagrids, weaving grids ect via list maniplation, culling, redirecting paths. Lately I have been exploring grid manipulations by moving points with attractors and sin functions, I am at work now but will upload mine later. Thanks.
