Here’s something interesting we spotted go live on iOS and Android’s app stores this week: Vodafone Firsts. It’s a smartphone app released by Vodafone and designed to be used at concerts – starting with a Booka Shade gig in Berlin later this month. The idea: to get people waving their phones in the air to create a synchronised light show. “Experience a show like no other as you, the audience, collaborate with the performers to create a sensory masterpiece,” as the app store listing puts it. “Get ready for the moment when the audience becomes an interactive part of the performance holding phones in the air to form a giant screen of light, imagery and sound. Simply wait for your cue from the stage, open the app and hit GO.” It’s not the first time this kind of thing has been tried: musician Dan Deacon did it back in 2012 with his own app (Bulletin, 29-Aug-12), while startups Makelight Interactive, Wham City Lights and WeGlow have all touted the idea in recent times. Judging by the in-app FAQ, it’s Makelight that is working with Vodafone on this new app.
