Image sharing apps are really popular, with Instagram probably at the top of the pile with it's mix of cool effects and easy sharing.
Viddy basically does this, but with video clips. You can shoot 15 seconds of video, or choose a 15 second video clip from any iPhone video, and share it via Facebook, Twitter or YouTube in seconds.
Once you've chosen your video, you can add effects like vintage, black and white or even '3D'. They may be a bit gimmicky, and the optional music isn't really worth using, but the end results can be quite pleasing.
