Number Theory Image: Hooks for Elementary Courses

[matqkks]

Are there any good images that can be used as a hook for an elementary number theory course?

Are you concerned that number theory itself ain't sexy enough?

 

[matqkks]

It is sexy enough but I am looking for something which will have an impact and motivate students.

Number theory is basically the theory of primes, so you could use their distribution graph, or that of twins, or just print out a large prime.

Another idea is something around encryption.

You might find some ideas on the 3blue1brown youtube series. He does some beautiful representations of numbers on the complex plane including the Riemann function and other cool stuff.

There was one on spirals and the apparent connection to prime numbers.
