‘Displayed on Adobe’s Almaden Tower, the San José Semaphore displays four wheels at four distinct positions — for a possibility of 256 combinations. The four wheels turn to new positions every 7.2 seconds.’

Sounds like quite a challenge…

‘San José Semaphore – New Contest!

There’s a new code in town. Here are the rules.

The successful decoder must identify the message and reveal the mechanism by which the message is encoded.

  1. You must show how you recorded the transmission, how you analyzed the message, and how you solved the cipher.
  2. You must document your process through notes, photographs, and computer source code (if you use any), and you must submit these materials with your claim.
  3. There are no restrictions on the methods you use to analyze and break the code, but you must show that you have done it honestly; use of inside information not available to any resourceful member of the public would be grounds for disqualification.

The decision to award the honor is at the discretion of Ben Rubin and Adobe representatives.

The first individual or team to crack the new code will be awarded bragging rights and a one-year subscription to Adobe® Creative Cloud™.’
