It would be great if we could use it for training with live measured data.
i feel like it would be better if it didn't have text that's clearly ai generated
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.<p>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
Hey HN, I built Spin Lab: a browser-based interactive explainer for table-tennis spin.<p>It visualizes topspin/backspin, spin rate, ball trajectory, bounce behavior, and why the opponent’s return reacts the way it does.<p>I built it because spin is central to table tennis, but most explanations are either too hand-wavy or too static. I wanted something you can scrub, slow down, and experiment with.
