Simulate Minecraft Redstone [Geometry Nodes]

Hey!
I have actually gotten all the help I needed so far for this project, from here and other places.
It's difficult to mark an answer as correct given how vague my question is, but I have gotten my question answered here.

If you still want to give it a go just for fun however (and because I would love to trick someone into learning some redstone)
Here is the best explanation I can give :

Minecraft operates on a grid of 1x1 tiles, and every block has to conform to this grid (redstone dust being no exception).

In this example the base geometry is a set of 1x1 faces as to respect said grid.
Another quirk of redstone, is that it has a Signal Strength / Power.

The signal strength can vary from 15 to 0, but how do you know which signal strength it should have?
Well, by default redstone has a signal strength of 0, no power.
If [x] is a redstone dust where x is the signal strength,
an 18 blocks long, straight line would look like this:

[0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0][0]

Right now, there is no power, so we need a power source, that is, assigning any signal strength to a chosen tile (or face, in this case).
If we chose the first redstone dust to have a power of 15, our line would suddenly look like this:

[15][14][13][12][11][10][9][8][7][6][5][4][3][2][1][0][0][0]

The power propagates from the source depleting by 1 for every tile it crosses, and stops going down once it reaches 0.
If the original power source was around the middle, and we gave it a power of 5, here is what our new line would look like.

[0][0][0][0][1][2][3][4][5][4][3][2][1][0][0][0][0][0]


This is how the signal strength changes, but what about the color?
It's pretty simple actually, for a pretty accurate representation of the color in game, you only have to worry about the red channel.
I found this simple equation to work wonderfully : 12*power + 10

Now for the other way redstone dust's textures dynamically change : Connections



This one is simpler to explain, redstone will visibly connect to any directly adjacent tile.

Starting from the top right and reading right to left and top to bottom :
The first one in the image above would be connected on all 4 sides, the second would have 3 (on the left, bottom and right), the third would have 2 (on the left and bottom).
The fourth one is special, it will either show if it has a connection on the top and bottom, or if it has a connection on either the top or the bottom.
(The fifth one is honestly irrelevant to the question and can be completely ignored)

Note that this isn't every possible case, but all of these can be rotated to create any possible case.
If we had a redstone dust with an adjacent to it's right and top, we could rotate the third one 180° to get what we need.


This about sums up redstone behavior for a flat plane.
If you want the textures to make this possible, or have anymore question, please contact me on discord, it would be a pleasure!
