Twitter launched a brand new iPhone app last night called Vine, which helps people share six-second looping video clips with sound to the social network, as well as to Facebook. Based on a video-sharing startup acquired by Twitter last year, Vine’s makers say the clips are “little windows into the people, settings, ideas and objects that make up your life. They’re quirky, and we think that’s part of what makes them so special”. Twitter co-founder Jack Dorsey went further: “Vine is the most exciting thing I’ve seen in a while. Not just because of the team, because it brings an entirely new art form to the world.” An entirely new art form if you’ve never seen an animated GIF, obviously. Still, we can see Vine catching on with music artists as a fun way to share mini-clips with fans: it’s tailor-made for just-long-enough-to-be-intriguing clips of new songs in the studio, as one example. Perhaps don’t film your kids dancing to a Prince song, mind.
