Lockscreen Magick is a script that uses ImageMagick to take a screenshot (or input file) of your desktop and add effects to it. It then takes this transformed image and sets it as the Login Background, which is effectively your lockscreen.
Currently only supports OSX.
It overwrites your current lockscreen picture but does save it as bak.png, in the same directory as the screenshots.
Make a directory called screenshots in ~/tmp/screenshots. Then run the script with sudo. Sudo is needed to overwrite the old lockscreen image.
You can change the percentage values that are used in the convert command. I suggest not going above 20% for the resize command as it takes quite a while.
Make sure to install ImageMagick.
You can installed with brew - brew install ImageMagick
