Here’s a fun discovery for the New Year. The world’s first 24-hour music video featuring Pharrell Williams’ song Happy, which was originally written for the movie Despicable Me 2.

It’s a theme and visual variations for a danceable pop song. The 4-minute piece repeats continuously for 24 hours, but each rendition features a different video of one or more people dancing to the song. If you watched one each day, it would take almost a year to watch all 360 of them.

If you click on the image below, your browser should open the video at the time that corresponds to your time of day.
