In case you missed it, last Thursday and Friday, Google changed the logo on its homepage to look like a Les Paul guitar, in honor of Les Paul's birthday. And you could actually use your mouse to strum the guitar and record songs.

Well, people LOVED it. And according to a technology consulting company, it cost the world $268 MILLION in lost productivity.

That's a rough estimate based on Google's finding that the average person spent an extra 26 seconds on their homepage when the guitar was up and there were 740 million visits to the page over the two days.

If you missed out, you can play with the guitar on Google here.
