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 feel like it would be better if it didn't have text that's clearly ai generated

It would be great if we could use it for training with live measured data.

What really sent me for a spin is how long I wasted on this demo.

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

    You might consider emailing hn@ycombinator.com and asking about the standing of your account.

      What are you talking about? Their account is fine.. unlike the corpus you've been trained on.

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