Every frame in this GIF is a 3,100-digit prime number:

Together, they recreate the world’s first motion picture: Eadweard Muybridge’s iconic 1878 “Galloping Horse.”
How it works: Each frame is converted into a grid of 1s and 8s, then slightly tweaked until the math clicks and a prime number is born. Fast primality tests spot the candidates, and rigorous checks confirm them.
The result? An animated piece of history, built entirely out of pure mathematics.
