DescriptionRandomly black odd numbers.png |
English: 200x200 spiral number grid with odd numbers that have a 23.38% chance of being coloured in black. Modified version of this script, but instead of colouring in all primes, colours in odd numbers randomly to show that seeing patterns in Ulam spirals isn't just pareidolia. ~23.38% of all odds <40,000 are prime. |
