Google I/O 2018

Google usually announces the dates of its annual developers' conference, Google I/O, via an alternate reality game or puzzle played on the web. In 2018, the game involved translating a tweet from binary and using Google Maps Street View to spot clues at the Google office which, when entered into various "locked doors," led the player to the Shoreline Amphitheater and the dates of the event: May 8–10.
