Hugh Manon, eaubscene on Flickr, has been on an amazing streak with his cachemash project. Cachmash is his, more elegant, term for the Photoshop Truncation Glitch, a bug in old versions of the program that can be exploited to create shattered images with a very particular look. It's a hacker's approach to glitching; a bug is discovered in the program, usually accidentally, and then exploited to generate a specific visual effect.

This excerpt from our piece on glitch for World Picture Journal applies well to this style:

The aesthetic of the glitch tends toward blockiness, toward crystalline fragmentation. Even an audio glitch creates the impression of edges. As many have noted, this opposes the “bleeding” or “warmth” we perceive in some forms of analog distortion (the famous advantage of tube amplifiers over solid state). This instantaneous fracturing is what glitch artists savor. The image crazed. A sound in shards.

The technique relies on a mishandling of truncated JPEG files. The missing data is filled in with what's in the cache. By simply flipping back and forth between a source image and truncated file, two pictures can be combined. Eaubscene has put this approach to good use, combining images with differnet colors, often giving a sense of depth and space, counteracting the often flat quality of this type of glitch image:
