Help with parametric brick curved wall with attractor

Hello, I'm trying to achieve something like this...

http://indulgy.com/post/V1oaK15VJ2/warehouse-renovation-by-archiuni...

I'm trying to get a stretcher bond brick wall(with hollow bricks) of 230x230x230mm which rotate according their proximity to a attractor.

To get the staggered pattern, I use a horizontal frame to connect with a centrebox. However, I want a hollow brick, so I specified it to a geometry container. However, I do not know how to attach the geometry container to the horizontal frame. I also do not know how to calculate the distance from the horizontal frame to the attractor point. 

Attached is my grasshopper and rhino file... I've currently attached the frame of the horizontal frame to the base plane of the centre block, but I want to attach a geometry to it instead. The attractor point system is disconnected on the right.

Thank you for any help!
