As the newly-announced start date for Google I/O 2015 approaches, we're sure to see plenty of easter eggs and hidden messages around Google's web properties, but one easter egg has already made itself known.

Google's I/O 2015 page links to an awesome Chrome experiment that lets users jam to (and edit) a catchy electronic loop with five unique instruments. Inside the experiment's source hides a dance partner - left shark.

Just hit F12 to open the dev console, run experiment.consoleDance() and enjoy an ASCII shark who's doing his best to keep up with the experiment's beat.


In the page's source code, a left shark mp4 also makes an appearance.

If you've already spotted other easter eggs, let us know. In the meantime, make sure you've set a reminder for March 17th when Google I/O registration officially opens up.
