About

Glitxt was kickstarted during Art Day Hack 2013 at LEAP Berlin. Related to the theme "going dark", we wanted a way to encode a message in a picture to conceal the text, but also make it obvious to the human eye that the image is hiding something. It is not an advanced encryption method, but it still makes it difficult for automated data mining programs to extract the message hidden in the image.

This is a project of Christopher Pietsch, Paul Vollmer, Tim Pulver
