>>3527255PS: to trigger the riddle of the oreston one needs to set the aperture to a value where the blades form a symmetric shape (they don't do that usually), one of the corners of the shape has to point to the word "rest" and the rest is about interpreting the other phrases/numbers correctly which are being pointed at by the corners of the hexagon, these consinst of the control number 5 (which is the aperture value which has to be set in order to gain the key shape) and reading words backwards and stuff. SPOILER ALERT DON'T READ The final result is the word "victoreyem" which means "glorious" or "winning" (adj.) or read as "victor I am" what means "the winner I am). The command which leads to this result is one to find a word rhyming with "kitpO".
Complete Spoiler:
1. Set the aperture to 5.
2. First corner is pointing at the word "rest", second will point at "ey" in "Meyer", third at a "k", it forms the word "key" if read backwards, that means that one proceeds further through reading things backwards.
3.If you read the word "Meyer" backwards you get "reyeM", "reim", "rhyme".
4. the next word pointed at is "Optik", which backwards is "kitpO", what we read is "rhyme kitpo"
5. The next word I would think of is "victo", which is the latin participle of "winning"
6. The suggested solution is "victoreyem"
I find this very weird but facing the fact that back then it was quite common to install gimmicks in sold products to make these more interesting it's not that surprising, it's for instance something similar to a seqence of released books where the backs of the books would make up a picture together.
