Sure, it’s nothing new for Google to change its logo, but today’s variation is particularly interesting because it’s in motion. Dozens of dots or balls makes up the standard blue, red, yellow, and green logo today. When you first load up Google.com, these dots are scattered all over the place but quickly fall into the Google logo. But when you move your mouse anywhere near this logo, the dots freak out and jump all over the page.
If you move the browser window around, the balls also move. These movements are based on the direction you move the window.
A number of people are noting they can’t see the logo, so you should try visiting the U.S. or British versions of Google to see it.
