3d rotation at an attractorpoint

hey there,
 i have a problem with my definition and i hope someone can help me.

i have a surface, where rhombuses are loftet with cells in it. an attractorpoint scales the size of the cells. the last thing i need is the other attractorpoint that should become the attention of the cells. all of the cells have to look at the point. i hope someone can help me out. my idea was to create a surface in the cells, then make the normal of the surface to look at the point but i don´t know how to rotate right with the 3d rotation.

Hi Grashüpfer, I think you'll want to use the Orient instead of the Rotate component. Notice that the curves (you made from the four cornerpts) are not planar, so to get a normal I for now simply used the surfaces midpts...
