Cereal
Only 10 people have ever solved this challenge (9 if you don't count bok, who created it), so its difficulty has got to be really high.
Looking at the pictures, one obvious approach would be to interpret them as ones and zeros, and then go from there. However, that would mean there are 251 bits of information here, which is an odd number in that it is not evenly divisible into bytes or nibbles. It is even a prime number.
I wonder what the "Cereal" is supposed to mean?

It is a hint, but in my opinion you can only understand it, if you know the solution.I wonder what the "Cereal" is supposed to mean?

Any hints here? I'm really stuck.

You won't believe it - i also started with the RS232 specs (because of the homophone of Cereal and Serial) and in the end it helped. Ok, you don't have to take the specs too precise, i played a lot with different settings (Start-Stop-Parity-Bits), but as i said, with all these attempts in the end i got the solution.
The bad thing is: The solution has nothing to do with the Serial Communication, but this you'll find out once you got it

Well no matter how many start-/stop-/parity bits you use for a data transmission, unless the transmission is incomplete you will have as the number of data given a multiple of an integer number, which can never be a prime.
On the other hand, there have been challenges with incomplete data - two or three of the "Didactic" ones, if I remember correctly. So maybe it is not actually intended that the number of bits given here is prime. Or it might be a red herring.

According to the suns and clouds are shown in the challenge, the answer maybe has something to do with the Cloud API from Sun Microsystems. There are resources defining interfaces and protocols. But how to apply the lopsided number of 251 bits? By the way, this approach has nothing to do in the CRYPTO section...
