By now, you've probably seen the huge zipper on Google's homepage when enter a search query. If not, it's definitely worth looking at. It's pretty interesting.
Google, often known for its quirky logos, cartoons, and drawings, has decided to honor the father of the modern-day zipper, Gideon Sundback, with its homepage design today. Except Sundback didn't invent the zipper. He actually invented what's known as the "Hookless No. 1" in 1914, which later evolved in to the zipper.
Still, this is one of the first Google gags (as I like to call them) that's actually interactive.
Google did a similar thing with Pac-Man a few years ago, and that later became a game that Google now hosts on its website, for free.
Google, for all its faults (Google+, Google Play, stagnant growth), does offer some interesting and innovative things to its homepage.
It's rare and refreshing to see that everything a company does it not always about the bottom line. Sometimes, it's just about making someone's day better.
