Looking for some help here!!!

I am reaching out to see if anyone can help me figure out how to creat these types of structures (see images). I am new to both Rhino & Grasshopper but can find my way around and can dreate some really neat objects. but for the life of me i can not figure out how to create things such as the images shown. can anyone help? maybe send me a basic or even complex grasshopper tree showing a similar type of modeling?

I find that I have been able to pick up on even complex modeling trees because i was able to look at them and dissect the process.

Thanks
