It's time to surrender another afternoon to an interactive Google doodle. The search engine has outdone itself in celebration of the late-Bob Moog's birthday. The electronic music pioneer was born on May 23rd, 1934. Seeing as how the anniversary isn't until tomorrow, the doodle hasn't actually hit our Google front page. Thanks to the magic of timezones, however, you can check it out on some of the company's many international sites, as our colleagues at Engadget Japanese pointed out. Google's really outdone itself here, you can play the synth doodle by tapping on the keys with your cursor, or by hitting the numbers on your keyboard. Naturally, there are plenty of knobs to fiddle with, and you can also record your musical experiments for posterity. Get switched-on with the music awesomeness in the source link below.
