This is a Processing program in Java that causes a video to appear glitchy, sort as if packets/frames are being dropped, but not exactly. It takes rectangular samples of each frame and moves them around randomly. It's not intended for anything particularly serious, but just a cool effect for artists.
Example output: https://vimeo.com/46671485
A window of controls allows you to tweak the effect as the video plays.
Tested under Processing 2.0.3 and both Java 1.6 and 1.7. In order to use Processing in Eclipse, I recommend you install Proclipsing
