another test anim. current issues. now that timescale impacts gravity in 2.83+ i find it harder to get a good curling wave. if i position the board anim based on particles, then the board ends up underwater when the mesh is generated. if i position based on mesh (as was done here), then the board isnt a consistent effector. anim is kind of janky, but i'm trying to find a good base method, then i'll work on the refinement.
