Every frame of this video is a prime number with 3100 digits. Additionally, this video is a recreation of the first ever motion picture, created by Eadweard Muybridge in 1878 at Stanford to study a horseâ€™s gallop.
The inspiration to create this motion picture came from a video on Numberphile I watched a few months ago about a very special prime: in 1996, James McKee was a mathematician departing Trinity Hall at Cambridge and wanted to honor the tradition of bestowing a farewell gift on the college, he devised a prime number that also depicted the University logo. After seeing the video I wrote a short python script to turn images into primes. The script takes an image and converts it into a sequence of 1â€™s and 8â€™s (1â€™s for the lighter parts of the image and 8â€™s for the darker parts). It then randomly changes a few digits in the image and tests for primality using the MillerRabin test. This test quickly excludes numbers that are not prime and finds out the ones that are more likely to be prime. Finally, you just need a method to verify the numbers that are actually prime in the group that was preselected using the MillerRabin test.
If you want to create your own prime images the code is available here.
A few open questions worth exploring later:

Are there any special compression/encryption properties for a video where every frame is a prime?

Would it be possible to have a similar video but in which if we join every frame one after the other into a single number, it would also result in a prime?
