Right as we thought news about Pharrell was starting to die off, here he goes again. Pharrell Williams made the first ever 24-hour-long music video. The interactive video detects the timeline you are in, and shows you the part of the video that corresponds to that time. If it is 4pm in Minneapolis, the video will start from then. You can then choose different parts of the video, and switch to parts that you like.
Here is the link to this nice little 24-hour project: http://24hoursofhappy.com/
