We’re also working on something like this, but we’re making a game around it https://charperbonaroo.github.io/bls/#0

Oh wow this is awesome. I got through the first few levels and would like to complete it later...

Also, is this the same as the 2015 'bitmap logic simulator'? I found this while reworking reso awhile back: https://realhet.wordpress.com/2015/09/02/bitmap-logic-simula...

Brilliant idea! That logo however is the most repulsive piece of artwork I've seen in a long time. (I am sorry for being blunt)

Nah it is indeed absolutely hideous. There's a higher-res version with less funky colors that I think looks a bit nicer: https://gitlab.com/lynnpepin/reso/-/raw/master/logo/reso_log...

I looooove this stuff! I'm sure you're aware, but here's some other related works I'm a fan of. https://esolangs.org/wiki/Turing_Paint https://esolangs.org/wiki/Piet https://esolangs.org/wiki/Drawfuck

Turing paint is a new one to me (and very interesting to me as well, because it sounds like it uses a similar approach under the hood.) Thank you for showing me these!!

As a complete layman I wonder if there’s a future where you could use a picture/X-ray of an old CPU architecture and simulate it blindly with an approach similar to yours?

I think it'd have to be a very different approach (unless it's an electron scan?) I'm not an electrical engineer though, so I'm in the layman camp as well!

If someone made that, I assume it'd use some computer vision to identify the individual components and the connections between them. After that, each component would need to have their individual simulator. (Unless x-rays can see individual semiconductors?)

That's neat. There's lots of interesting circuit simulators on the web now, but has anyone ever seen a toy/simple simulator for VLSI devices? Something where you could draw in metal/poly/whatever layers to create and simulate transistors?

Zachtronics has a lot of good games in this area. I haven't played this one, but Shenzhen I/O might scratch this itch too: https://www.zachtronics.com/shenzhen-io/

The project is super cool but I agree the logo is a terrible example of it in use. I'd love to see a more easy to digest example. The logo circuit is confusing and I'm not sure what to make of it.
