Satisfying and addictive toy-like physics
From 4 comments
Love this! It's highly addictive. (No guilt)
Quizzical4230 on HNso satisfying.
karanveer on HNi love this. it reminds me of simpler times when we’d have iphone apps/games that would explore a single mechanic and implement it really well.
prodigycorp on HNAs a phone user, I hate you, I hate how good this is. That counter is just mocking me.

Simple web toy without sign-in or paid tiers
From 2 comments
This reminds me why simple single-purpose web toys used to be so satisfying. No account, no onboarding, no "upgrade to pro" - just a thing that does one thing well. The world…
analogears on HNAmazing to see software like this without sign-in requirements or paid subscriptions!

Nostalgic and funny
From 2 comments
That’s got to be one of the most satisfying things ever. The real device was a darling invention and this is a faithful recreation of the experience of being in time out in the…
reactordev on HNI 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 :-)

Objections
Sound is not physics-based and sometimes mismatches the motion
From 3 comments
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.
aetherspawn on HNI noticed that the boing sound gets deeper and lower with smaller-magnitude boings. Is the boing audio generated procedurally/realistically in response to the physics of the…
ethmarks on HNIs this physics based audio?

Spring does not bend or rotate realistically
From 1 comment
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…

I have no sound on ff ios, volume 100%

Add a synthesized boing sound
From 2 comments
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.
aetherspawn on HNIt's not, unfortunately. I'd love to find a synthesized version of a boing sound. Perhaps some folks with modular experience could chime in?

Can we add accelerometer support? :D

Is it unminified or open source?
From 1 comment
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…

Elastomania and X-Moto wobbly physics games
From 2 comments
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…

Jelly Car
From 1 comment
Wait. Is Jelly Car basically a rethinking of this? I never managed to have the elasto games, but looking at the trailer, there’s a lot of similarities.
