Pharrell Williams released a new music video for his song "Happy" on Friday, and you could watch it all day long...literally. Directed by We Are From L.A. and produced by Iconoclast, it's the first ever interactive 24-hour music video.
Throughout the virtual day you'll see a lot of random people, and some celebrities too, dancing around the streets of Los Angeles, while lip synching the song. The jam can be found on the "Despicable Me 2" soundtrack.
Experience the full-length video at 24HoursOfHappy.com, or check out the shorter version if you don't have all day.
Oh, and don't worry if you missed the launch at midnight. You can pause, rewind, fast forward and even share a moment on the clock through Twitter or Facebook.
Warning: The track will make you very happy and probably get stuck in your head for the rest of the day.
