pnglitch_webapp is an FCGI program for "glitching" PNG image files. This program was made for a school project, and a demo can be found here. This project was inspired by The art of PNG Glitch.
Execute make in the project's root directory.
This program requires a properly configured FCGI compatible webserver to be useful. If you would like a more practical, commandline version of this program to run yourself, see this other repository.
