I think this actually produces HDR on my iPhone 15 Pro, which really makes it pop because not a lot of things do

Very cool!

If I stir a cup (or even a rectangle) of water, it will start swirling. Why does this not swirl? Local chaos, dissipates quickly, bulk flow does not sustain.

Swirls on my phone.

It looks really nice and is very smooth.. But a subscription for a fluid dynamic app, really?

I tried phone, similar. I guess it kind of does keep rotating, but you can’t see it. Colors fade faster than flow.

If you dab a finger in the stream at right angles to the flow you made, the splash flows the expected way, but maybe slower than water.

It would be good to visualize any flow. And also to respond to device orientation so you can feed the resonance :)

The first time I've actually appreciated my laptop's touch screen.

They gave you a free web version. So if they want to try and do a subscription of charge $30 for a one off purchase I think that’s up to them. I’m curious if anyone will ever buy a subscription or spend $30 though.
