I know this is coming late in the day, but I couldn’t let this occasion pass without mentioning it: Today marks what would be Jules Verne‘s 183rd birthday.

As with many special occasions, Google has created one of their popular doodles in celebration, this one being an interactive nautical theme referencing the author’s popular novel, 20,000 Leagues under the Sea.

There’s a lever on the right side of the logo that allows you to control the doodle submarine, but what I didn’t realize is that, according to The Telegraph, if you view it on an iPad or iPhone, you can tilt the device to have the water level move in any direction you want!
