In my online undergraduate P5.js course, students are about to begin the module on motion and physics, including a bit of physics simulation using Matter.js.

@bloody_albatross If we're talking about improving the code, then I'd be more interested in the question of how to get a stable tower to stand up in a physics sim without bouncing all over the place and collapsing spontaneously. In this demo I use a cheap hack of freezing all the blocks until you actually click on one of them. Presumably it's really hard to get this working correctly (cc @topher_batty)
@csk @topher_batty I feel like that is basically what all games do anyway. Also saves CPU.

It suddenly occurred to me that I had never seen anybody put together this particular demo before, and I realized it had to be done.

@csk This is incredibly satisfying to table-flip. My day needed this. Thank you.

@bloody_albatross @csk Paul Kry even had a paper where they sort of generalize the freezing idea to merging together collections of rigid bodies whose relative motion is small enough. https://eulaliecoevoet.github.io/AdaptiveMerging/

@bloody_albatross @csk I'm not sure of the latest and greatest in academic rigid body stacking, but I've used Danny Kaufman's 2008 staggered projections scheme successfully for one paper: https://www.cs.ubc.ca/labs/sensorimotor/projects/sp_sigasia08/KSJP08.pdf Downside is you usually need to start bringing in better LCP or QP solvers.

@csk excellent vibe coding simulator!

@csk Turned out great! Thanks for sharing

@csk Wonderful!
I made your code even messier by introducing a small... let's say "typographic" improvement:
p5.js Web Editor
A web editor for p5.js, a JavaScript library with the goal of making coding accessible to artists, designers, educators, and beginners.

This one has a lot of optional ways to destabilize the system. Pick up a tiny block from the top, don't drop it, and watch the instability move through the carefully balanced system-- over and over.

@csk Great!
When will we get a version with this?

@lenaschimmel That's amazing, thanks!

@csk This interactive version is amazing!
I just wanted to note that @ahl at least animated this for an episode of Oxide and Friends about the XZ backdoor.

@csk I love the idea, but it's unstable in its base config already. Just clicking into the image changes the setup.

@csk also, recently I said I'd been nerdsniped and one of my younger colleagues asked what I meant; I dropped a link to https://xkcd.com/356/ and then realised it's *19 years old* (so is the "I know regular expressions" one)...so came out before he could read...how did we get so old? A warning for showing this to students
@bazzargh @csk https://xkcd.com/435/ My favorite, which I regularly show my physics students.
