I've already got the app. It's awesome guys. I will say though I hope the app store search allows you just to search 'vine' because I had to search 'vine made' to get the app to show.
http://vine.co/blog says "Today we're launching Vine... Vine has been acquired by Twitter." So that was fast.
Please tell me what this does on your website. Some kind of demo would be nice, too :D
