Happy 16th birthday, Google Doodle!

Google Doodle is now on its 16th year. It celebrated its birthday last Saturday and features a quirky animated Google Doodle.

The doodle features the G in Google's logo while measuring the growth of the O and L.

The uniqueness of Google art has already celebrated a lot of events around the world. It made doodles out of various people, events, and causes over the years. Of course, the topics are well-varied as well. From sci-fi show Doctor Who to iconic actress Audrey Hepburn to birthdays of scientists, and musicians.

Google Doodle also immerses itself to different social causes including International Women's Day, the Sochi Winter Olympics gay-rights controversy and the 50th anniversary of Martin Luther King Jr.'s "I Have a Dream" speech.

It even featured the start of fall season!

Over the years, Google has been really creative and technically ambitious with its Doodles.

The company teamed up with NPR radio program This American Life for Valentine's Day, a playable guitar in honor of Les Paul and a working Rubix cube.

And who would even forget the Pac-Man Google Doodle that helped to forget the work stress in 2010.

We expect more from Google Doodle. We expect more creative and interactive doodles in the coming years. Cheers, Google Doodle!
