Last year, the theme of I/O was bringing Android everywhere: to autos, wearables, and beyond. This year, the website reflects the Material Design look that Android embraced. But no schedule for events has been posted so far.

The website also includes a Chrome experiment. By clicking a settings button, you can access a page that lets you create music by connecting dots with virtual string. Moving your mouse over the strings strums them, as if you were playing a guitar.

Google I/O is traditionally one of the most-watched developer events of the year, featuring big new announcements and occasional stunts from Google executives. In 2012, Google famously demonstrated Project Glass by having skydivers livestream their jump onto the roof of Moscone Center.
