glitchlock: a glitch art themed randomized lockscreen. powered by swaylock.
i (xero) do glitch art for fun. i was messing around w/ one of my shell scripts and thought: this would make a cool lockscreen! after a bit of research and refactoring here we are.
this is a fork of the original work by xero and modified to work on Wayland by crablab.
the script takes a screenshot, then datamoshes it. optionally overlays an image (one for each display) then uses that image as the background for the lockscreen.
this lockscreen has the potential for information leakage, since it uses a screenshot of your active screen. i made this for fun and personal use, please take care and weigh your opsec and personal threat model before deciding to use this.
an example workaround would be setting up your screen very nicely w/o any secret info in it and taking a screenshot. then replace line #9 in the script (grim /tmp/lock.png) with a command to {move,copy} your pre-setup screenshot into place (e.g. cp ~/lib/img/lock.png /tmp/lock.png) then let the script randomly glitch that image out everytime.

these are available on aur and apt. mileage on your package manager may vary.
if called alone, the script will take a screenshot and glitch it. but you can optionally pass an environment variable named GLITCHICON to the app and it will center that image on each display and overlay it on the glitched image.
an example of calling the script on MOD4+ESC using sxhkd
# lockscreen
mod4 + Escape
GLITCHICON=~/src/glitchlock/stop.png ~/bin/glitchlock
