I've been using #AnnotatedEquations in my recent papers. I think it really adds to the readability and understanding of the math.

Here are some examples. It uses #tikz in #latex.

Let me know if you like it. Happy for any feedback.

@sibin This is brilliant, thanks for sharing! I'll definitely be using this for some upcoming conference talks, and sharing it with my colleagues 😄
@johnabs thanks! Hope it works out well for you. If you follow the “thread” there’s a Latex package as well.
