There was a perl solution already some years ago
posted in perlmonks, it reads:
#!/usr/bin/perl
$r=25; $c=80;
$xr=6;$yr=3;$xc=-0.5;$dw=$z=-4/
100;local$";while($q=$dr=rand()
/7){$w+=$dw;$_=join$/,map{$Y=$_*
$yr/$r;
join"" ,map{$ x=$_*$
xr/$c;($ x,$y)= ($xc+$x
*cos($ w)-$Y* sin$w,$yc+
$x*sin ($w)+$Y*cos
$w);$ e=-1;$ a=$b=0
;($a,$b) =($u-$v+$x,2*$a* $b+$y) while(
$ u=$a*$ a)+($v=$b*$b)<4.5 &&++$e <15;if (($e>$
q&&$e< 15)||($e==$q and rand() <$dr)) {$q=$e;($d0,$d1) =($x,$
y); } chr(+( 32,96,+ 46,45,43,58,73,37 ,36,64
,32)[$ e/1.5] );}(-$ c/2)..($c/2)-1;} (-$r/2
)..($ r/2)-1;select$", $",$", 0.015; system
$^O=~m ~[wW]in~x?"cls": "clear";print ;$xc=(
$d0+15 *$xc)/16;$yc=($ d1+15*$yc)/ 16;$_*=
1+$z for $xr,$yr;$dw *=-1 if rand
()<0.02; (++$i%110 )||($z*=-1)}
which is a “Mandelbrot explorer”.
(It rotates, zooms in & out, and scrolls randomly to examine regions
of the Mandelbrot set it deems “interesting.”, according to
it’s creator.)
It doesn’t exactly follow the specs named here but
makes an interesting entry (imho). Maybe a simple
Mandlebrot is not very interesting for the perl gods ;.-)
