# BASH - <s>167</s> 165

The `mb3` file:

    eval g={-4096..4096..200}'
    'h={-8192..4096..115}'
    x=0;y=0;for((i=0;i<30&&x*x+y*y<1<<26;i++))
    do((v=((x*x-y*y)>>12)+h))
    ((y=((x*y)>>11)+g))
    x=$v
    done
    printf $[i%10]
    '

(no trailing newline)

Run it in a terminal with line length 107:

# BASH - <s>214</s> 190

    for h in {-4096..4096..200};do
    for g in {-8192..4096..115};do
    x=0;y=0
    for((i=0;i<30&&x*x+y*y<1<<26;i++));do((v=((x*x-y*y)>>12)+g));((y=((x*y)>>11)+h))
    x=$v
    done;printf $[i%10];done;echo;done

This basically is the same code like below with calculations being replaced by hardcoded values and the image got flipped around the x axis.

Use this source, Luke:

    a=-8601;b=2867;c=-4915;d=4915
    ((e=(b-a)/99));((f=(d-c)/49))
    for((h=d;h>=c;h-=f));do
    for((g=a;g<=b;g+=e));do
    x=0;y=0
    for((i=0;i<30&&x*x+y*y<1<<26;i++));do((v=((x*x-y*y)>>12)+g))
    ((y=((x*y)>>11)+h));x=$v
    done
    printf $[i%10]
    done;echo;done

This code uses integer arithmetic only, so BASH does not need additional helpers for doing floating point maths...
