Continuing my recent fascination/obsession with different forms of temporal distortion, I dug up this video, which was the first one I saw that used slit-scan photography to create temporal displacement. Many people have employed this technique in interesting amusing ways, but this one exceeds all for general creepy weirdness. (I apologize if this drops in an advertisement. It's worth it.)
I know, her attire makes it just that much more creepy, but having viewed a few videos that use this technique, I'll attest that the effect is much more striking when we see people's actual limbs.
If you wonder what you're looking at, the technique is creating a time difference between the top of the frame and the bottom. Each line of video, from the bottom up, lags slightly behind the one below it. This creates a time difference of several seconds recorded within each frame.
