    > I figured out what would be a reasonable amount to spend on the project and then multiplied that by 10.

    I like the way you think.

    Totally off-topic, and I may be wrong, but I immediately loved the non-LLM writing-style and felt glued to the content just through the writing alone. It's getting rare.

    I saw one in a computer museum in Switzerland. It was a much larger field, it was just large orange LEDs (or were they tubes?), but it also cycled between a dozen of different cell automata games. Something about being able to see individual "pixels" made it really mesmerizing.

    When I was a teenager, I read a book about assembly language for the commodore and implemented the game of life in a really simple way. I just used the text screen. To switch on a cell, I would put an asterisk ('*') in it. Then I could run my machine code program and it would evolve according to the rules of the game of life.

      And who didn't do that! :)

      You could also 4x the resolution by using half- and quarter-block characters from the top half of the ASCII table (or it'd be the PETSCII one i C64 case).

    A thousand bucks for 17x17 touchscreen. Add a painting frame, hang it on the wall, and you made yourself amazing art for cheap.

    My Alma matter has a jumbo version of this, in which the game if life is one of several available mode https://en.wikipedia.org/wiki/BioWall

    I love this and would love to see it on a wall at our office or something like that. Maybe there's smaller/cheaper led/switches that would work in a handheld version.

    Très cool.

    A grid of capacitive touch sensors could be printed directly on the pcb, bringing down costs by a degree of magnitude. Real switches are much more satisfying though.

      I want to do a game like lights out. I'm thinking in 3d printing transparent caps and using dirt chip pcb switches and standard leds. The cost must be also down to 30 cts. Would be like a middle ground.

    Nice. A friend of mine just picked up a Linnstrument, and I’m very tempted to create a Conway’s Game of Life-based musical visualization for it.

    I wonder is there a version GoL where every bit on a computer-display or LCD TV is one cell? How does it look?
    • alex_duf 2 hours ago
      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.

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

      One window = one pixel.

    I've always wanted something like this board, buttons which can light up (preferably a few colours), to use to make games. Anyone ever found such a board which is hackable / programmable?
    • rmnclmnt 2 hours ago
      Novation Launchpad used to be exactly that: you send MIDI CC messages with proper values and you can light up the grid (with different colors).

      Did that a few years back, i guess this might still be possible

      https://www.adafruit.com/category/280, they're ready made from 4x4 to 16x8 but in theory you can just put more modules into an enclosure.

    That's not a "physical" version of game of life -- that's a digital version, like every version, but with bigger pixels.

    I don't want to build this or pay for it, but I really want to mess with it for an hour.

      You need a science museum!

    Would be interesting to do this with people and observe the inevitable mistakes they make.

    Now that would be simulating life witg life.

    • ordu 19 minutes ago
      Well, people can die if they have too many or too little of neighbors, but they can't be summoned from a thin air if they have just enough neighbors. Hard to simulate life with people. Though if you are ready for a simulation step of 20 years or so... But it still may not work, because you need people of two opposing sexes and compatible genders near the empty sell to fill it. In Game of Life all cells are hermaphrodites.

      But I agree mistakes might be fun to watch.
