Whenever you have 24 hours to spare or simply need a doze of infectious happiness, make sure to watch the epic pick-your-protagonist promo, specially made by We Are from L.A and Iconoclast Interactive for Pharrell Williams. Up to this point, the longest interactive music video experience yet, but it definitely works in smaller doses as well! And if you want to know what not to miss from this 24-hour experience, here’s a recap of the greatest moments, courtesy of the NME blog. This  mega production featuring 4oo dancing extras, filmed across eight miles of L.A and during eleven days, seems to be reinventing not only interactive music videos, but promos in general. Though we think the low budgets  have certainly pushed the limits of creativity and artistry in the music video field, it’s refreshing to see popular artists walk the Michael Jackson path and be willing to promote their music in a big way! So kudos to Pharrell! You can check out below also the linear version.
