Semaphore consists of four ten-foot wide illuminated disks that rotate to a new position every eight seconds.
With four wheels and four positions each, Semaphore has a vocabulary of 256 possible combinations, creating a way of communicating its encrypted message, known only to the artist and those involved with the installation.
Cracking Semaphore's coded message will be posed as a challenge for the public.
Stay tuned until August 7 when the puzzle will be unveiled atop the Adobe San Jose building.
