Today's question is:

Hint: There are no randomness. There are no magic numbers in my code (except for the paper's width, height and an

*2*)

Here is a close-up of the graphics:

I struggled to show the interesting mathematical interesting structures and got this:

It contains some magic numbers (for folding, spacing etc.) but more easy to understand than the first 'pure' graphics.

Without a high-resolution version of the complete (or at least the upper left corner) of the artwork it seems hard to guess.

Oh, it is very good question. The upper left corner is the most important part of the artwork. It helps you to solve the quiz.

I would say that this figure the last bit or the sum parity of some 2D function, am I close ?It is reciprocal numbers in binary notation. 1/2 = 0.1, 1/3 = 0.01010101..., 1/4 = 0.01, 1/5 = 0.00110011, etc. I omit preceding 0s, and make 0 as black, 1 as white. Left-most column corresponts to 1/2.
