    lock.sh -l -c cmatrix           # Run cmatrix as lock screen and need to login to unlock
    lock.sh -l -t 10 cmatrix        # Run cmatrix then will invoke login if run over 10 seconds
    lock.sh -a zebra                # Show the 'zebra' ascii art on lock screen
    lock.sh -d art -a zebra         # Find 'zebra' ascii art in 'art' directory and
                                    # show it on the lock screen

                                    # by default, or will invoke login screen
    lock.sh -S 5 one two three      # Shuffle every 5 seconds with args
