I wasn't hearing the sound initially so I thought it wasn't working in Firefox. Put the sound all the way up and boinged again. Made me jump out of my seat. Hilarious :-)

I have no sound on ff ios, volume 100%

Funny thing: this feels "realistic" because it’s not perfect physics. A perfectly simulated Hooke's law spring actually looks fake and too stiff. But if you let the animation wobble a bit more and slow down the damping, our brain reads it as weight and squishiness. It’s basically controlled sloppiness.

Same is true in a lot of old platformer games. Real physics feels horrible.

TIL I don't know how to “unmute” my device anymore. My new-ish iPhone doesn't have a physical switch on the side and I can’t find it in the settings in the pulldown menu.

Oh good point sorry. If you open the Control Center (drag down from the top left, typically), there should be a bell icon..?

That, or Settings -> Sounds & Haptics -> Silent Mode ?

Any consideration on sharing the unminified code? I was a bit curious to read through the code and it seems like such a shame to keep it obfuscated. From a quick perusal, it seems like the bulk of the code comes from howler.js (a sound library), and the core functionality is conveniently implemented below the mobile template.

Of course! https://github.com/gregsadetsky/boing

The sound is not physics based, the boing sound keeps going if you grab the head, likewise sometimes the sound ends before the vibration finishes.

Well spotted! I'd love a synthesized version - if anyone has pointers.

Make sure to unmute your device - either using the physical mute rocker on older iPhones, or by disabling Silent Mode (tap the bell in the Control Center)
