According to Mashable, Twitter has unleashed a new mobile service called Vine, allowing its users to create and share videos. Vine is able to capture video for up to 6 seconds and includes stop-motion videos through which you can include as many scenes possible. Along with the video, users also have the option of including audio. While Vine is an application separate from Twitter, videos are able to be uploaded onto Vine as well as Twitter.
This fun app is available for free on both the iPhone and iPod Touch and is currently limited to mobile use only.
