Pharrell Williams recently contributed a song to the soundtrack of animated film, Despicable Me 2. Now he’s revealed a video for that track, “Happy”, but with a twist.

Williams, who’s been breaking records this year with his huge-selling features with Daft Punk and Robin Thicke, has created what he’s calling the “world’s first 24-hour music video”. Basically, this is an interactive video where you can skip to a different time of the day and watch the clip continue playing seamlessly in an alternate setting.

The video features cameos from Odd Future, Steve Carell, Jimmy Kimmel and more. Watch it here and try to spot them all.
