CrowdGlow.

CrowdGlow makes you a part of the light show at supported live events! If you're at an event that supports CrowdGlow, open this app when the show begins and your phone will magically come to life and become part of the light show on stage! If you would like to find out how you can use CrowdGlow at a concert or event that you are planning, please head over to http://crowdglow.uk to find out more. Please share your photos and video of CrowdGlow in action using the hashtag #crowdglow
