You've probably noticed today's interactive Google Doodle -- a playable, recordable synthesizer in honor of Robert Moog’s 78th birthday. It's also no coincidence that productivity has likely been down this morning.
Internet users have already shown a wide range of talented, creative Moog Doodle examples, as YouTube user FableA2 shows us in the video above. Some have created their own covers and original songs, but this one impressively syncs with the Doctor Who theme song.
