Google will being registration for its important developers conference, Google I/O, at 7 a.m. PT on March 27, with the event taking place June 27 through 29 at the Moscone Center in San Francisco.

Last year at I/O, Google introduced Android 4.0 Ice Cream Sandwich, which took the Android OS in a smart new direction. It also used the conference to talk up Chrome browser advancement, to introduce Angry Birds on Chrome, and to show off its Chromebook laptops.

Last year’s tickets for I/O sold out in less than an hour, so demand for the event this year will no doubt be similar or even higher. Set your alarms developers because we know how you like to stay up late and work.

To promote this year’s event, Google developers have created a fun, interactive game called Input/Output where you can build your own elaborate ball-tossing machine. (Hit the arrow button in the bottom right corner to dig into the source code.) Google will be picking the best machines created with the tool and show them at the conference
