Today's Google is a world first, because it's the first Doodle that has some sort of 360-degree VR-compatible functionality. It's also a celebration of classic French filmmaker Georges Méliès, who's now probably best known for his work on A Trip to the Moon and The Impossible Voyage in the early 1900s.
If you head over to the Google homepage today you'll see the animated Doodle has a big play button in the middle, and while that's not out of the ordinary hitting play will open up a 360-degree YouTube video that you could drag around and watch in your browser. But that's not as fun or interesting, which is why Google has put the doodle into the Cardboard and Daydream-compatible Spotlight app (available on Android, iOS). For those of you with a fancy headset, the Doodle is also available in a stand-alone app on both Steam and Viveport. Or alternatively you can watch the embedded video below:
The Doodle was developed by Helene Leroux, a doodler living in London, who originally wanted to blend animation and live action as a tribute to the man who helped pioneer special effects and other things we take for granted like the jump cut, timelapses, as well as the science fiction genre. Instead Google encouraged her to make a VR film, which was in turn developed with help from Google's Spotlight Stories and Nexus Studios. As usual you can watch mote about how the Doodle was made below.
