Check out this neat little trick on the Google I/O site

If you know Google, you know that the company isn’t averse to building a few neat little tricks into its products.

Now it looks like it’s taken the same kind of attitude into the site for its annual I/O developers’ conference. If you click on the images of an “I” and an “O” on the site, you’ll find yourself escorted to a new page, each of which is themed to play a sound effect.

It’s a neat little bit of fun, although cracking the various codes can get a little frustrating at times. The ones we have managed to crack make it worth it though.

There’s a space page:

An instruments page:

The single-player pong page:

According to The Next Web, there’s also a bowling page and an eight-bit page, although we haven’t been able to find those yet.

If you want to get going without all the hard work of figuring the code out, here’s a hint for one of the pages: IIOIOOII.

Let us know if you manage to find any other kickass pages.
