Gleitzsch

A tool to generate glitch art.

According the Wikipedia the glitch art "is the practice of using digital or analog errors for aesthetic purposes by either corrupting digital data or physically manipulating electronic devices". This particular tool compresses an image as mp3 sound file and decompresses it back into a glitched image. During this process it also might apply a variety of different filters.

Usage

To run the program you need:

• all python libraries listed in requirements.txt installed
• lame installed

Lame can be obtained at: http://lame.sourceforge.net/.

You can use it with both command line and web interfaces.

Web interface

Just run:

./runserver.py

Then open http://0.0.0.0:5000 in a browser.

Then something like this should appear:

Functionality of this version covers almost all options of the CLI.
