Today on Google is a fancy interactive logo for the would be 78th birthday of Bob Moog. Moog invented the first electric music machine known as the Moog Synthesizer.
He revolutionized music with this device when he introduced it in 1964 at a convention.
To celebrate his life, he died in 2005 at the age of 71, Google has created a very cool interactive logo. You can virtually play the Moog Synthesizer on Google's home page.
Google has a detailed explanation of how to operate. Here is that picture:
You can clearly make at the Google letters in the logo, which make it a Google Doodle.
Plus, you can record your music, play it over and share it with friends on Google+ or via a short URL.
