Show HN: Spin Lab

[dead]

Why? It all makes sense.

That being said on my cell phone, I can’t make heads or tails of this. Nothing really works.

I don't think the issue is that they used ai behind the scenes, but there is an implicit proof of work from forcing it beyond the style you'd expect. I for one roll my eyes whenever I see that specific kind of rounded corner, frosted glass ui and layout choices. It looks like someone trying to superficially/ham-fistedly trying to replicate "good taste" without actually having a good model of taste, its quite uncanny/bootleg.

120 rev/s on backspin = professional loop :D

I feel like the topic just scratches the surface; there are many more things that are way more interesting to talk about here.

For example: air density actually matters. Professional players sometimes struggle to make shots in different parts of the world. The balls are not the same either. Comparing DHS with Nittaku, for example, they have different properties and a different bounce. In my part of the world, DHS is the preferred ball, compared to the US, where, at least where I’ve been, they prefer Nittaku balls.

Now about the content:

The Bounce: This could have shown all three balls at the same time, instead of showing them one after another. That would make the effect clearer.

The Answer: This feels a bit odd, and I think something in the calculation is wrong because the usual push always goes over the table on backspin.

Overall, I get that this is a very simple representation of what table tennis is, but it gives me “I did it in 5 minutes with AI” vibes.

I know nothing about table tennis, but love it visually! Awesome job
