The non-repeating thing is bullshit. Sure, pi is a non-repeating decimal. But individual groups of numbers repeat. It is strongly suspected that pi is normal, and an n-digit sequence will repeat on average every 10^n digits. So, the artist has been clever and made the algorithm rely on some value of n larger than six, which doesn’t guarantee no repeats in itself (they probably checked) or, being a clever bod made each new section dependent on all the previous digits. I mean, they wouldn’t have done what you imply in the article and used each digit individually, because that would repeat on digit four. Would they?
