Perhaps explore plotting the Ulam spiral too? https://en.wikipedia.org/wiki/Ulam_spiral https://en.wikipedia.org/wiki/Ulam_spiral
Of course the pressing question is, if this is the start field for a Conway game-of-life, do any interesting patterns evolve?
It would be fun to brute-force a few starting grid sizes and seeing how long the game continues. Games that last more than a few steps can be set aside for human evaluation.
Because if it turns out that some particular smallish grid or spiral of primes causes something interesting to happen in game-of-life, then you can imagine HN melting down!?

- madcaptenor 1y agoSeconding the Ulam spiral. My first thought was "why can't I see the diagonals?" because I expected it to be the Ulam spiral.
- BrainBacon 1y agoNot exactly the same, but I made this Ulam spiral generator more than a decade ago. https://embed.plnkr.co/mdZX6C/ https://embed.plnkr.co/mdZX6C/ It isn't just doing primes though, instead the size of the dot generated is dependent on the number of even divisors for the number at that position.
