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.

Confused. Perfect physics means perfectly simulating reality, not perfectly simulating an unreal idealized formula. Are you saying Hooke's law doesn't feel realistic or are you saying a simulator for a realistic spring doesn't feel realistic?

Elasto Mania is a great game from decades ago (but still for sale!) that exploits this fact to a hilarious extent. You control a motor bike with excessively wobbly physics making all kinds of stunts possible (and necessary, to complete the levels) that are spectacular and surprising.

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 ?

I just got an iPhone 17, and presumably because it inherited its Control Centre configuration from the 13 it replaces (which had a physical switch) the silent mode toggle was not present. Tap and hold in an empty space to edit the controls and add it in.

It doesnt boing rotationally, only in a straight line. Like the spring isn't really there.

If I bend it right round to one side so the spring is curved I expect it to bounce round to the other side.

This takes me back a few years when the first of my Uni friends had a baby, they spoiled him with so many toys that their lounge room was like an obstacle field where you had to be careful where to step, but despite all his toys the baby spent all his time while I was there playing with the door spring.

There's something therapeutic about door springs, that you just have to stop and play with it.

Oh it needs a total boings by everyone counter!

alright, I implemented a world boing counter :-) thanks for the great idea

maybe also de-boing the boining now that it's calling the server. i think the js script pasted here will show you it's needed
