Show HN: Spin Lab

#1
Hey HN, I built Spin Lab: a browser-based interactive explainer for table-tennis spin. It visualizes topspin/backspin, spin rate, ball trajectory, bounce behavior, and why the opponent’s return reacts the way it does. I built it because spin is central to table tennis, but most explanations are either too hand-wavy or too static.

Thanks Fable, we miss you

I opened it on mobile, the first window shows up and the text cannot be scrolled through.

Also absolutely horrible UI and seems like you just put up whatever Fable shat out without checking or any thought. I am only saying this because you shared it for public feedback

Are you using flight trajectories with simulated drag and lift from Magnus effect?
