Google has been actively doodling on each day of the London Olympics 2012 and this doodle is clearly one of our favourites. This, however, also isn't the first time that Google has gone interactive with its doodles. On May 23, this year, Google had a doodle dedicated to the inventor of the Moog synthesizer, Robert Moog. The Doodle featured a synthsizer which you can either play by clicking on the keys or by typing on your computer keyboard. The sharps and flats (black notes) are played with the numbers on your keyboard and the regular notes with the letters. The sound that emanates is electronic and you can adjust the pitch by using the pitch wheel on the left. You can record your composition by hitting the record button on the right and play back your composition. You can also share your work on Google+.

 On similar lines was the doodle that Google dedicated to Les Paul, inventor of the solid body electric guitar. The doodle could be strung like a guitar and if you placed your cursor over a string, you could hear the string being strummed. Users had the opportunity to have fun with this, by making chord combinations with the strings on the left and vary them up with the strings on the right. There was even a keyboard option which when you turn on, certain alphabets from your keyboard would strum certain strings. We played around with the melody that certain words would form. When we typed "Google" and "Android" the melody was only meh. "Apple" for some bizarre reason sounded like a workable melody.
