Just press the green flag (or press shift & press the green flag for Turbo Mode) to see a Ulam Spiral with primes shown! {Look up Ulam Spiral; Numberphile has a great video on it} As you can see, the Prime Numbers are not random. They actually show up more often on some diagonals/horizontals/verticals than on others! (Each diagonal/horizontal/vertical line can be expressed by a different quadratic equation (y = a*x^2 + b*x + c))
I made a simple sprite to create an Ulam Spiral; but instead of entering in 10,000 Prime Numbers myself, I decided to use Wes64's automatic Prime Number Generator to enter them!
