In honor of American electrical engineer Robert Moog (1934-2005), Google has created a very special doodle on what would have been his 78th birthday. Visit the search engine's homepage to check out a customizable, playable and even recordable digital version of Moog's namesake, the game-changing Moog Synthesizer.

In a 2000 interview, Moog said, "I'm an engineer. I see myself as a toolmaker and the musicians are my customers. They use my tools."

Popularized such musicians as Stevie Wonder, the Moog was one of the most important advances in music during the latter half of the 20th century. Google is honoring that legacy by giving its users the opportunity to try out some of the instrument's most-beloved features -- including the mixer, oscillator, filter and envelope.

Google even put their own humorous spin on the instrument, changing the name "Moog" to "Goog" for the special Google Doodle, which displays an old-school, likely wood-panelled Moog synthesizer hooked into a reel-to-reel machine.

The Google Doodle was officially available on Wednesday, but die-hard Moog fans could play the digital instrument a day early by visiting Google Japan's homepage here.

Google Doodles have offered a wide range of fun opportunities over the years, from an interactive Pac Man game to a playable 'guitar' in honor of Les Paul, but the search website and its top-notch engineers outdid themselves this time, creating one of the coolest and most impressive features to ever grace the search giant's homepage.

Google's Chief Doodler Ryan Germick and Google Engineer Joey Hurst set out to create today's Google after realizing that they are both big Moog fans. The goal was to "Pay tribute to someone who was like a patron saint of the nerdy arts," Germick told Mashable.

According to Germick, the project was originally conceived as a challenge of sorts.

"Joey is an amazing engineer and I love to come up with a way to stump him," he added.
