hexagon on surface

Hi guys,

I made this "eyes" based on hexagon cells on a deformed surface. I wand them to react to the curvature of the surface, so that the hexagons are smaller in the curved parts and larger in the straight parts.

I'm running out of ideas. I tried to project it to a mesh or a surface, or to set it up with a hexagonal grid that is modified by an attractor, but I couldn't make it. In the end it should be applied to a more complex surface, like a dome.

I'm looking forward to your suggestions.

thank you,

Rupert
