This has been used as a xlock puzzle image in 1995 the first time. Remember: Many of them are good but mislead by the brutal. Others do not want the truth to be revealed.
This is jpg to save space. Convert this into XPM e.g via xv or
ImageMagick´s convert. Then put it somewhere and
include an alias into your ~/.bashrc e.g. like the following:
alias xlape='xlock -bitmap somewhere/cprpa.xpm -mode puzzle'
