Glitchmonkey allows those of us who are either non-geeks or semi-geeks to prepare visual material with artifacts - known as 'glitch-es":

I've used this script for a while and it works quite well on most images. If you want to add it to your own work - then I suggest you upload your original (in private view) to a photo uploading site, enable glitch monkey, and re-download for further manipulation.

Enjoy ;-)

Brilliant, enjoyable idea :)
