If you're ever been a fan of stop motion video or time lapsed images, you definitely need to check out Watch it Change. This app turns your iPhone into a production studio for this kind of media, complete with tips and tricks on exactly how one would accomplish all of this.
When you first load up the app, you'll realize that there really isn't that much there. The developers have provided two videos, each one showcasing stop motion videos that they have produced with their iPhone. You can share those videos with your friends and even download more from the website. Plus you have the ability to create your own.
Pressing the create button brings you to what looks like a slideshow editor. Basically you'll have the ability to load up your camera and take your stop motion pictures. Then place them in the correct order, set the frame rate and tweak a few other features. Once that's done your video will be set to watch. You can even upload it to their website.
This is the ultimate bored-in-a-cubicle app. You could easily have hours of fun with this app and actually have something to show for it. Unless your job already requires you to do stop motion video, you should definitely pick this app up.
