light-up wristbands synced to concert music

3 Jul

This is kind of cool:

At concerts, Coldplay uses custom light-up wristbands synced to the music to promote an upcoming DVD.  They’re controlled by radio signals to keep them synced.

I always love getting light up items when I’m somewhere at night in a crowd.  We always used to get them for special events at basketball games in college.  From light-up pompoms to light-up bam bams, they always made the crowd glitter, which looked spectacular when the lights were dimmed.
