How to built a shape by GH?

I want to build a Parameterization city shelters，and it will be Interactive with user，every unit modules on it could move Rhythmically.

I already finished the Modeling by rhino, and i really know nothing about how to use Grasshopper to break up the unit modules as parameterization. Is there any Grasshopper Master could help me? The result i want is looks cool and easy to build.

The question：

1，In the video，How to process parametric form？（kangaroo？）

2，After make all the things on the round surface, how to change the Tangency circle into flat polygon?

3, at last ,how to link every unit module？

Much obliged,
See the video portion of the simulation should use kangaroo, but smaller portions but the curvature of analog form still do not understand, I hope to attract attention to study together
