Sorry if this doesn't belong here, but I do think this is math-related. I stumbled upon a interesting looking picture a while ago (I think it was either on Stackexchange or Reddit), and I had saved it to my desktop. I recall that it had some mathematical meaning to it (I think I remember a caption saying "this picture is the ... of roots of ...") or something.
Here is the picture:

    A reverse image search yields this page with the caption An exponential sum. – Gribouillis Sep 04 '17 at 11:18
  • Thanks. Strange. Reverse google image search was the first thing I tried; but it gave me nothing.
    I really think I saw it on Stackexchange some time within the last couple of months, and it had to do with some roots.     – Natash1 Sep 04 '17 at 11:20

I have found the explanation on this page. The author, David Angell says that this is the graph of

$$\sum_{n=1}^{10620} e^{2 \pi i f(n)}$$ where $$ f(n) = \frac{n}{dd}+\frac{n^2}{mm}+\frac{n^3}{yy} $$ where $dd, mm, yy$ are the values corresponding to his date of birth. Partial sums are computed and consecutive complex values are joined by a straight line segment.
