Google this morning kickstarted its annual I/O developer conference with a keynote full of surprises. Prior to that 9am presentation, however, the company was running a nice teaser over at the official Google I/O page.

With each passing second the numbers would fall apart into dozes of dots bouncing off the screen edges. Missed that finale? No problem, Google has you covered with a Chrome Experiment that allows you to rewatch the last twenty seconds of the countdown.
