It's not easy Bing green. Microsoft has unveiled the first HTML5 animated home page for its search engine and Google rival Bing.com, and it's got a frog on it.
The Bing page features the usual search box, backed by a looping video of a white-lined leaf frog padding along a branch in Manu National Park, Peru. We have no idea why.
The page adds an interactive and informative twist to the famous Google doodle, which alters the Google logo for a day. If you mouse over the picture, hotspots reveal information about our amphibious friends, warning that the prettiest frogs are often the deadliest, and there's a video on diamagnetism, which causes frogs to fly when subjected to strong magnetic fields.
There's also some froggy trivia questions about Baron Greenback and, er, Frank Bruno.
It's nice to start your day with some random trivia. Google has been doing it for a while, commissioning special versions of its logo on the search home page that are themed to something happening that day.
Many celebrate pioneering heroes of science and technology, such as Marie Curie, steam-powered badass Richard Trevithick, and Edmond Halley of Halley's Comet fame. Then there's artists such as Muppet man Jim Henson and Mr Man Roger Hargreaves. But our favourites are the HTML5 animated doodles, including the Les Paul playable guitar and the suitably outrageous Freddie Mercury extravaganza.
