From the beginning
This was a first contact with Grasshopper and Rhino for me. I attended the PN3 course during coronavirus lockdown. That means I had one more source: course book, YouTube and video recording of the course itself. In combination of these three sources I find a way how to work with attractors. As you already know I was new in the Grasshopper world. Till I could find a way I try to use what I have learned. As a result, I got a facade panels with bubbles which are changing their size according to a position of sun.
