Hey there!
Great work with the mod suite, I like how it adds direly needed complexity to the vanilla production chains!

However, have you considered using the "Finely Crafted Graphics" mod for the machines? (https://mods.factorio.com/mod/finely-crafted-graphics).
It's great work in general, but I am especially concerned about the pulveriser, as it feels a little bit unintuitive having the "Crusher" and "Pulveriser" both look the same, especially if you play with the "Muluna" mod, where you will actually have pulverisers and crushers on the same surface.

I see that the graphics provided by "Finely Crafted Graphics" have a different footprint, but it shouldn't be too much of an issue considering your mod suite is just getting started?

Thanks for the heads up, I'll have a look at them.

Those are fantastic graphics and I will definitely be using some of them. Not sure if any of them resemble a pulveriser/crusher. Did you have one of them in mind?

Glad to hear you like them!

So I did a bit backtracking and found the original Author, Hurricane (https://www.reddit.com/user/Hurricane046/), who also exhibits his work including animations on figma (https://www.figma.com/proto/y1IQG08ZG2jIeJ5sTyF4MP/Factorio-Buildings?node-id=14934-304&node-type=frame&t=tk88gXWNIga60zMr-0&scaling=scale-down-width&content-scaling=fixed&page-id=0%3A1&starting-point-node-id=2585%3A1158&hotspot-hints=0&hide-ui=1).

Anyway, now that I see them animated I see the issue. I was thinking the "Fuel Refinery" or "Scrubber" might still fit? They both have some sort of separation and shredding theme to them.

Ditto, they look great on figma.
I thought scrubber might fit but rescaling it to fit 2x3 would look odd. I think they all have a square format with large round parts that would look odd in a different format.
I'm a bit concerned that if I made the pulveriser a different shape, say 3x3, current users may not like having to rebuild.

Yeah I totally see your issue with rebuilding there. Rescaling would also look really odd.
Personally, I would not mind rebuilding, but I might be the odd one out here.

Maybe it's not worth the hassle just for the looks, but I will keep an eye open, maybe I will find something with a matching footprint.

Cheers
