Six short films from the book The Prime Clock, for anyone who was told at school they weren't a maths person. No formulas on screen — just counting, and watching.
Part 1 — Are the prime numbers really chaos? (8 minutes)
Everyone says the primes are random. This film starts there and asks one small question: what does the last digit of a prime do? Every prime past 5 ends in 1, 3, 7 or 9 — and once you see that, the list stops looking like noise.

It proves nothing and predicts nothing. It's a way of seeing something you already knew — and Part 6 is honest about the limits. If you think I've got something wrong, say so in the comments; that's what they're for.
