Not only a brilliant use of common web-based tech, but a nice experiment in collaboration between artist and fans.
The clip descrip from YouTube:
"This music video was shot for Sour's 'Hibi no Neiro' (Tone of everyday) from their first mini album 'Water Flavor EP'. The cast were selected from the actual Sour fan base, from many countries around the world. Each person and scene was filmed purely via webcam.
