Does anyone know of more examples of water simulations in WebGL? I’m looking for ways to implement waves with foam.

I love Evan’s Pool demo. https://madebyevan.com/webgl-water/

Was reading somewhere that one isn't a simulation. Rather super clever tricks to make it look like water, swimming pool, a thing in it.

You're right. Move the ball so it's half-immersed, wait for the water to settle, and then cause a single ripple. The ripple will propagate past the ball, coming out the other side with no diffraction.

Still very, very cool.

"The Find My network is approaching a billion Apple devices and can detect Bluetooth signals from a lost AirTag and relay the location back to its owner, all in the background, anonymously and privately." Is a feature like this already in use?

Yep, has been active since iOS 13 I think.

Your service looks really nice with a clean design. I will give it a try.

Best of luck

Interesting approach. You know them openasapp? They also try to sit on top of a sheet to create apps
