We've seen so many slick and beautifully manicured iPhone apps over the years that it's rare to be wowed by a newcomer. However, Vine does just that when you first pop it open, immediately launching a brief shared video clip without hesitation. And assuming you have a half-decent Wi-Fi or cellular signal going, it simply doesn't stop as you scroll down the feed, with each subsequent six-seconds-or-less clip loading quickly and without prompt, giving you a very small window into the life of whoever was on the other side of that iPhone. Finally, somebody nailed the Instagram-for-video concept. Granted, that "somebody" is Twitter.
Boinx Software's iStopMotion is a great tool for creating stop motion movies using a camera connected directly to your Mac. This tool got much better today, however, with update 2.5. The update adds enhanced support for Canon cameras, better iMovie export options, tilt shift filter, and even color correction.
