Google home page a big colorful mystery

Have you been to Google today? Then you’ve noticed that they’re running another special logo. The word “Google” is formed by a bunch of colorful circles that scatter all over the place when you mouse over them. Unlike other special logos that commemorate holidays or historical events, this one doesn’t have an easy explanation. There’s been talk that it’s for the anniversary of Google or the rollout of HTML5 but the company denies that that’s what it is. And they won’t say why it’s there.
