I was exploring an ancient garden. It seems the original inhabitants had long since left. One of the trees particularly struck me. Besides the delicious-looking red fruit the branches were twisted into a strange configuration as though the tree were trying to tell me something.
I made a detailed sketch and took it home to discuss with my friend.
"So, that's exactly how the tree was growing?"
"Yes, a separate branch reaching off to the right, and everything all kind of jumbled up in the middle. I'm not sure how to make much sense of anything!"
"It's interesting, don't you think, that the upper branches look almost the same as the lower ones, but a bit smaller?"
"Now you mention it, I suppose they do, and almost everything within each cluster seems to be leaning either to the left or the right."
"How was the fruit - did you try some?"
"Well, I thought I'd better find out more about the tree first - never know what I might end up eating otherwise! Actually I brought back several of the fruits, maybe only some of them are safe?"
"A tree grows its structure from the bottom, but the energy flows from the tips of the uppermost leaves downwards, so it makes sense that there could be some difference between the upper and lower fruits."
I think we can just about tell which branch each leaf is attached to despite it all looking a bit jumbled...
What can we find out about the tree? Are any of the fruits good to eat? Is the tree telling us anything about what happened to the original inhabitants of the garden?
Hint (after Lukas Rotter has already solved the main part of the puzzle):
knowledge served a dual purpose - first as a major hint to the "theme", and secondly to suggest that the answer to the specific questions posed is within "general knowledge" and/or searchable on the internet, rather than this puzzle.
Credit [giving away major part of answer] to:
Florian F for the puzzle The maze one should not enter - this puzzle was a result of my thinking about different framings of a similarly simple code to make the fact that a 5 bit code was involved more discoverable, without being too "in your face".
