If venturing to Google today, one will find a Google Doodle comprised of portholes looking out at gently bobbing waves, celebrating the birthday of Jules Verne, author of noted works Twenty Thousand Leagues Under the Sea, A Journey to the Center of the Earth, and Around the World in Eighty Days. Pretty Doodle? Of course--but see that lever to the right of the ocean view? It's manipulatable with a mouse, and allows one to waste away their work hours on a Google Doodle undersea voyage. Be sure not to let go of the lever, or else it'll automatically revert back to the middle and you may not be attacked by the giant squid lurking in the Doodle's depths.
UPDATE: If you're on a newish MacBook and using Chrome as your browser, you can pick up your laptop and move it around, controlling the lever on the Doodle.
