I've been doing the 28 day Grasshopper Challenge course, and honestly, it feels like someone finally cracked the code for learning Grasshopper without crying into your keyboard. The daily mix of drawing, making little models, and reflecting somehow turns parametric thinking into something...fun? It's gentle, brilliantly structured, and sneaks fundamentals into your brain before you realise it. It's not just great for beginners, intermediate users will get a hugh amount out of it too. Its such a cleverly designed course that it really deserves the attention and support of anyone interested in mastering Grasshopper.

This exercise proved for me that even the simplest Grasshopper steps can give complex and elegant outcomes.

I have just started the '28 Day Grasshopper Challenge' this month and wanted to share some words related with it. From the very first day, I realized this was no ordinary task. Ertunç asks you to create a geometry/model, but he makes you aware of the steps you take while creating this model. He also helps you create the model by giving you the necessary instructions in advance, but he doesn't overwhelm you with strict sets of instructions. What makes the course unique is that you don't use Grasshopper at first to create these models. You build your idea with pencil, paper, and scissors according to your own rules. I like this!

I spent months building this challenge, and today is the final 24 hours of the Black Friday offer. So here’s everything in one simple, transparent post. You’ve probably seen these already, but here’s the full roadmap again: 🟩 7-Day Challenge 🟨 14-Day Challenge 🟧 21-Day Challenge 🟦 28-Day Challenge And together, these four phases give you 4 real portfolio projects. Not exercises. Not random forms. Actual spreads you can use to apply for computational design roles. You also unlock the full 10-Year Bonus Pack (20+ courses, ML bundle, automation tools, Rhino/GH files, studio diagrams, templates… around 35 GB). This one stays with you forever. Tomorrow 9 am ET (extended deadline for Skool) is the deadline to join with the Black Friday price. $299 at the link https://www.skool.com/grasshopper3d-lab-6917/classroom/6587fa18?md=50fc53b1bfcf462fb6c7dcb6086c2e71 $259 if you prefer PayPal Name: @ertunch I am only sending this because of time zones, not to pressure anyone. If it helps your learning, I’d be glad to have you inside. If not, I will continue to create free content here for you anyway. Best, Ertunc

I took a quick glance at Ertunç’s latest course, and the material is genuinely superb. The way he breaks geometry into clear, digestible pieces is what many try to achieve but usually abandon somewhere between the first vector and mild existential crisis. He goes a step further by pairing each idea with mockups and a hands-on workflow, making the logic easy to grasp while bringing AI into the mix without letting it hijack our ability to think. It’s a strong direction with a lot of potential, and it highlights exactly why his approach to parametric algorithms stands out. Thanks for the opportunity!
