Engineer explains the encrypted sky lights that confused Americans
An American software engineer successfully decoded an encrypted message transmitted via optical signals above the Adobe building in San Jose. The image being broadcast was a flower from Sandro Botticelli's painting "Birth of Venus." The project, which relies on an old SeMaFor system, uses a technique of transmitting information through four illuminated circles that change their states every 7.2 seconds to form digital patterns, which are then converted into a comprehensible digital image. This puzzle is the latest in a series of cultural and artistic messages that began with an encoded text and novel in 2006. It combines art, technology, and encryption displayed on the facade of a public building.
