Coldplay has been turning its audience into interactive participants at recent concerts by handing them Xylobands, LED-illuminated wristbands that can be activated using a radio signal.

The wristbands come in a variety of colors and have the Twitter hashtag #coldplayfilm printed on them to promote the band's live DVD. When turned on at certain points during the concert, the audience is illuminated with multicolored twinkling lights.

The Xylobands help to create a sense of community between the fans and connect them to the artist. After the concerts, they can either recycle the wristbands onsite or keep them free of charge. See what they look like in action in the video below:
