Nice program, Ocie.  Here is the command line for the period 4 midget.
I called your program asciiman.

./asciiman -o -0.16 1.035 -r 0.03 -l 1024

This produced the following.


    `
        _.,_s
        T@@@@@i   ,_gs_  mm
        8@@@@@A_W@@@@@@@m@f
         VM@@M@@@@@@@@@@@@@i
            i@@@@@@@@@@@@@@@=
           ,@@@@@@@@@@@@@@@@L
            @@@@@@@@@@@@@@@*
           ~M@@@@@@@@@@@@7`
            'M@@@@@@@@@@@`
            imW@@@@@@@@@~
            !*f` !~~@~`


Some others to try:
./asciiman -o -1.256 0.38 -r 0.01 -l 1024
./asciiman -o -0.0442 0.98658 -r 0.01 -l 1024
./asciiman -o -0.198 1.1003 -r 0.003 -l 1024
./asciiman -o  0.3592 0.643 -r 0.02 -l 1024
