Well, truthfully recognizing a function like that is a bit more like 
doing well in a mathematical version of Trivial Pursuit; fun, but not to 
be confused with actually knowing anything deep about the topic at hand 
(at least in my case).

Also, I like the pun.

Yeah, I'm with you. I've been keeping Wolfram's open in another tab while
reading this thread. There's so much to learn and so little time...

  I was going to suggest it because it looked familiar, but then I
looked at the image at http://en.wikipedia.org/wiki/Riemann_zeta_function
and decided that perhaps it's not that after all. The ridges looked too
evenly shaped.

I imagine that this image is from the x >= 0 half plane, and since the 
structure that's most obvious in the wikipedia article is for x < 0 it's 
  reasonable that this image would look different.  But yeah, I get your 
point, that very same issue is why I was pretty unsure if my guess was 
correct.

Yes, the real part is from 0 to 2, and the imaginary part from about 20 to 50.
Oh, and sorry for hijacking your thread--I enjoyed your quiz enough to try and
return the favor though.

Ramdom matrix?

I see a binary 2D matrix, checked in black squares to 0 allways and white
squares distributed randomly beetween 0 or 1.

Ricky, I liked your variation so much that I made a quick variation of it...

Rob -

And I liked your variation on my variation so much that I made a quick variation
of it.  One factor to unite them all...

Haha! This is a "prime" example of how religious zealotry can "spiral" out of
control around "one" small thing, even the smallest of factors... Bravo!

Completely random, but this image reminded me of a very similar image I once
rendered. Mine has none of the psuedo-order of primes in it, though.
