It's an artistic technique that allows you to fast-forward through time and it's absolutely fascinating to watch.  We're talking about time-lapse photography. This simple art of taking images every second over an extended period of time and then replaying the images in normal speed creates a feeling of moving through time.  Today's Gotta Watch features some of our favorite time-lapse videos, inspired by a video we posted Tuesday that shows an incredible view of the Northern Lights in Denmark. In case you missed it, the video is at the end of this post.

One frame at a time  - In 2010 we asked iReporters from around the world to submit videos of a single day through time-lapse photography.  You've gotta watch what we put together.
