Like a Rolling Stone
This interactive video of Pharrell Williams' 'Happy' from Despicable Me 2 is being touted as “the world’s first 24-hour music video". I recommend playing around with the full-version of the song on the website that features a clock. It has many well-known actors dancing through the streets at different times of the day.
While you are at it, also watch the new interactive version of Bob Dylan's 'Like a Rolling Stone'. The video allows you to flip through 16 television channels (they plan to add more), featuring everything from cooking shows to newsrooms, with well-known actors lip-syncing the song. It has over an hour of content, if you watch every video. But, if you stick to toggling the channels as intended, no two viewings of the song are the same. In a way, it is speaks to a real phenomenon. Dylan's 48-year old song is still everywhere, and plays at least once a day on some radio station or TV channel somewhere in the world. There are not many songs that are as enduring and ubiquitous, or remaining entrenched in pop-culture as Like a Rolling Stone.
I am a huge fan of interactive content, be it children's pop-up books, animated graphic novels, video games, flash videos, or web design… so it's exciting to see more artists experimenting with it in music videos. There's nothing more absorbing in the storytelling world, than when you get to play a role in the narration.
