Hi, this week I finally managed to make a much smaller version of the fibonacci algorithm in a visual flow : What helped, is to be able to define variables inside a flow and use them in an expression, even if the variables are defined in nodes that comes after the expression node in where they are used. In this case it's an array variable node that is needed. Something that I currently am trying to accomplish is creating visual flows that are smaller and therefore hopefully clearer and more helpful in explaining algorithms. In my previous visual implementations of the Fibonacci algorithm much more nodes and connections where needed not helping in explaning the algortihm (in the thread I have shared a previous implementation). I think this new approach helps and I'll explore this further. * update * after uploading the video I got another idea that helps showing the invisible connections between the nodes: when the array/list-node elements are read or an item is added.. a small rectangle around the element now flashes 😎 .. so I've re-uploaded the video

I want the addition operation to have two edges coming from the list, and for those numbers to flow to the addition operation in the same way the new answer flows forward. I want that on an emotional level, having no idea if it is helpful. 🙃

I want to prevent having too much connections to prevent "spaghetti" and to make clearer what is happening I've added the small flashing borders when the cells are read. I hope that makes sense 😊
