# 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?

• i guess size of each block represent a number and they are from $1$ to $9$. e.g. upper-left block is $3*1$ so it's number should be $3$. – Rafe Sep 16 '14 at 6:08
• "as part of a stained-glass window"... does the "part" that is your puzzle exactly correspond to the picture? – TheRubberDuck 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. – MattClarke Sep 17 '14 at 0:24
• Hey, come up with some more of these! – d'alar'cop Nov 1 '14 at 15:09
• I thought it was a green elephant with blue clothes and a yellow crown, LOL. – Kevin Voorn Jan 27 '15 at 12:51

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).
