# Chaos and Order: a visual puzzle in stained glass

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?

• "as part of a stained-glass window"... does the "part" that is your puzzle exactly correspond to the picture? Sep 16 '14 at 12:48
• @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. Sep 17 '14 at 0:24

• I thought it was a green elephant with blue clothes and a yellow crown, LOL. Jan 27 '15 at 12:51
• @AlwaysConfused - it is a decimal point Jun 3 '20 at 23:16

Solved it! Spoilers ahead:

Superposition of and

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 :-)

• indeed. interesting puzzle! +1 to both

• and what does red point mean? Sep 16 '14 at 15:31
• @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). Sep 16 '14 at 15:33
• 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. Sep 17 '14 at 0:29
