FWIW, here is a little graph I did a while back:

https://plus.google.com/101799841244447089430/posts/YeVfh7q5rD5

Here is a excerpt:
_______________________________________________
  this graph is based on the x and y axis representing their respective 
primes. So the point (0,4) would the the 1st and 5th prime numbers. The 
point (1, 3) would the be the 2nd and 4th prime numbers. The color is 
based on how far apart they are from each other. So, the distance of 
point (0, 1) would be abs(2 - 3).

I see some "wavy" squares all over the place. There is some sort of 
structure in the "prime color monitor"?

Humm...
