the second link you sent is the one I was talking about in my post. May have to try it out to slow it down. I have actually built something similar to what I am talking about physically, but I wanted to make it digital. When I built the physical version of it I didn’t have a board with it. We just used a grid square type board. Even if I followed that one guy the squares wouldn’t be octagon like I want them. Know of any youtube links that can describe how to make a octagon surface?
