A unique photo tour of Google's biggest, most spectacular developer event yet.

Google changed the game with its I/O 2016 conference, held last week in Northern California. In contrast to the traditional indoor conference of past years, the outdoor, festival-themed event brought not just the usual sessions and presentations, but quirky demo areas outdoor meeting spaces.

As such, the traditional firehose of news posts doesn't quite convey the spirit of this year's I/O, and so we've put together an extensive photo tour of this year's developer festival. Read on to get a look at I/O 2016 from the inside.

Google I/O 2016 took place at the Shoreline Amphitheater in Google's hometown of Mountain View, Calif. — a large concert venue located a short walk away from the company's headquarters.

Attendees walked away with an assortment of I/O-branded swag, including sunglasses, water bottles and a festival-themed t-shirt.

The keynote itself kicked off on the morning of Tuesday, May 19 on the Amphitheater's main stage.

The crowds were kept entertained in the run up to the keynote by a performance from Electronic musican Robert DeLong and two harpists staged high above the audience.

Android Central Editor-in-Chief Phil Nickinson streams on Facebook live as we prepare for the start of the I/O keynote.
