I wonder is there a version GoL where every bit on a computer-display or LCD TV is one cell? How does it look?

I did something like this: a 64x64 (4K) display of GoL (among other things) using addressable pixels. Alas, I only took one video when the display was working and it wasn't fully cleaned up: https://photos.app.goo.gl/WUmVgBVVi6rXDqSB7

Do you mean every pixel or every sub-pixel? Sub-pixel is interesting because the geometry of the grid isn't going to be the same from one screen to the other. It might also look compressed horizontally.

How many bits per pixel are you assuming, and are you imagining the red pixels are vertical neighbors with corresponding red pixels above and below, etc.?

Should be easy to do on my phone: https://itch.io/post/15723528

Good point to explore

At 8 bpp the effect is only colors moving vertically, up and down. After a while digging into it I realize why: most colors are too dark to be visible, we only see the most significant bits in each channel. And when those bits influence left or right the consequences are not visible.

Maybe I should try 2bpp. Or some HSL where I can clamp L.

Edit: Oh yes, it's interesting at 2bpp!

Conversely, it'd be cool to play it on an large empty office building.

One window = one pixel.

Right but what if every window was an outward pointing LCD screen each having their own node-per-pixel GoL !:_)
