surface population with attractor

Hi everyone,

I am new to grasshopper and I have managed to get this box morph to work on a surface but I am having trouble figuring out how to add an attractor point to affect the geometry.

These are the steps I think that I will need to follow: any suggestions are appreciated

1. create surface- ref in grasshopper

2. create geometry - ref in grasshopper

3. morph geometry to surface-

4. apply attractor point

5. smooth using image sample?

here are a couple of screen shots of what I have currently:

Please any help, suggestions, tutorials, or definitions are much appreciated.

Thanks

Jeff
