I found the images and I'm not very experienced at grasshopper. I've done basic morphing, but that's about it. I was wondering if someone could briefly explain to me how these forms are generated.
I think that when you want to modify some geometry, you must begins one step lower: if you want to modify surfaces is good to think about modify curves that generates that surfaces; if you think about curves, try to modify points that generates it, and so on.
First trnasformations are only rotations and a closed loft (i think).
