This is a music video for "Hibi no Neiro" (Tone of everyday) by Sour. The people in it are fans of the band, and the whole thing was shot on webcams all over the world. At first, you think that using fans and webcams would be the cheap and easy way to produce a video, but then you see the result and realize how challenging this must have been to coordinate and edit. -via Metafilter
