xkcd 2916: The Credible Machine

[Rinzler89]

For anyone wondering, this is a go at "The Incredible Machine" game series that was popular 20-30 years ago.

Looks like the page was renamed to just 'Machine'. I don't know why that would be. Surely not a copyright issue?

Also, I enjoyed the similar Crazy Machines, that has more modern versions available: https://en.wikipedia.org/wiki/Crazy_Machines

Ok, so this uses https://rapier.rs/ which is very cool

Rapier, alongside https://nalgebra.org/ (which it uses underneath) has seriously good documentation and some advanced features like cross-platform determinism (something made hard by the way floating point differs between platforms)

As usual, I am too dumb to understand this.

the balls go in and want to go out. top right there is a wrench icon. click that and gain access to some tools, with which you can guide the green and blue balls into their respective destinations. how fanciful the machine to guide the balls is up to you.

Appears to time release additional parts to use. Good Job trophy and cup as interactive objects, with rabbit and cat as decoration (although they do hide objects).

Been interesting to see the technique development over the release. People discovering jammed pipes and item combinations with some pretty clear progression of ideas among designs. One halfpipe, and then a bunch of loopdy-loops.

If Munroe, Goodhart, davean et. al. read this, one cool addition would be object hard points on other objects for attachments. Like a steering wheel with rotating repulsors. Fan speed adjustment would also be nice like the repulsor strength.
