I added a reduced preview of this to my blog post. I really like how it gives an impression of finding Waldo in a haystack of noise, just like in the picture books. The preview is …

That's awesome!

PS. The fact that any image can be encoded in 32 bytes this way implies that there are only 2^256 possible images — about one hundred and sixteen quattuorvigintillion. That's obvio…

You can have infinite and nonrepeating sequences which don't contain every possible subsequence. For instance, 1010010001000... (where there is one more zero each time) never repea…

You're right, that's a mistake! It should be the 92,296,989th through 92,300,940th bits. Yes, I did only search at 4-bit aligned bytes. Doing otherwise would be more complicated, m…

That's a cool egg! It's been a long time since I read Contact. Are the aliens supposed to have hacked the geometry of the universe to make the pattern show up in π?

Yes, to an extent that would work. 1) Take target image 2) Find the index in π (say) where a matchable sequence of bytes occur, like for Waldo. (If your image is big, this could ta…

But the probability of you actually finding where that string occurs before the sun goes nova is much, much smaller.

Yes, it helps to have more unique values. We want each repeated byte to occur in part of the pattern where a color also repeats. What I do is search for substrings with the fewest …

The part that's from π is the actual pixel data, which is extracted in the Python snippet "waldo.tobytes()". More-or-less equivalently, you could use "list(waldo.getdata())". The G…

That's still a choice of palette; you'll find it listed on Wikipedia [1] under "Regular RGB palettes". There's no doubt it's a much more objective choice than the one I used! I did…
