I created a visual puzzle, which my wife then implemented as part of a stained-glass window. I've no idea if it is (a) obvious, (b) stupid or hopefully (c) extremely clever, and hence would love to hear your opinion.

Here's a photo. What does it represent?

    $\begingroup$ "as part of a stained-glass window"... does the "part" that is your puzzle exactly correspond to the picture? $\endgroup$ Commented Sep 16, 2014 at 12:48

    $\begingroup$ @EnvisionAndDevelop: yes, the photo is just a part of the whole window. The whole window is much larger, with this photo being roughly the top-right quarter. The other three-quarters of the window is not relevant to the puzzle. $\endgroup$

1 Answer 1


Solved it! Spoilers ahead:

Superposition of blue and yellow

It's a combination of two numbers represented in yellow and blue panes, with green panes indicating where they overlap. The blue panes give the digits of $\pi$ (3, 1, 4, 1, 5, 9, 2, 6, 5) and the yellow panes are the digits of the first Feigenbaum constant (4, 6, 6, 9, 2, 0, 1, 6, 1).

P.S. I think this window is brilliant :-)

  • $\begingroup$ indeed. interesting puzzle! +1 to both $\endgroup$

    $\begingroup$ @klm123 The two numbers relate to the title of this question, and as Rafe suggested, the red dot marks the starting point (or perhaps a decimal point). $\endgroup$

    $\begingroup$ Thanks for the compliment @squeamishossifrage. I only wish it had taken you a bit longer to decipher -- I thought it was a harder puzzle than that! And yes, I think of the red dot as a decimal point. $\endgroup$
