Generates this pixel art of Rainbow Dash (it will be named "$0.bmp"). Requires Perl v5.14 (see below for a more compatible version). Can't be run from the command line, must be stored in a file (without trailing newlines). Strict and warning compliant. Only tested under Strawberry Perl.

    Out of curiosity I used the 'download' link and tested it using Strawberry Perl but got the following:
    Bareword found where operator expected at line 21, near "qw`&JAP +X]//gr" (Might be a runaway multi-line // string starting on line 19) Can't modify constant item in substitution (s///) at line 32, ne +ar "qw`&JA PX]//gr#xP/ #MP[\J]PEFXGHIP/ #MP{}JP P__/ #MZPAC| #MPDB/ #MZP| #MP| #Mw| #Mw| #M/ #/ # " syntax error at line 32, near "qw`&JAPX]//gr#xP/ #MP[\J]PEFXGHIP/ #MP{}JP P__/ #MZPAC| #MPDB/ #MZP| #MP| #Mw| #Mw| #M/ #/ # " Execution of aborted due to compilation errors.

    Did the closing quote mark was lost somewhere underway? I'm not ashamed to say I don't really understand what's going on here :-)

    -- Time flies when you don't know what you're doing
      Your version of perl seems to believe that the s/// ends right before the qw`, which is wrong. The qw` is supposed to be inside the s///, that's why there's no need for a closing backtick. I must admit I have no idea why it doesn't work for you. I tested both the download link and the copy-paste with Strawberry Perl 5.14.2. Here is a (hopefully) more compatible version, thanks to Anonymous :
      $_='ope n P+I0;priPnt (HP PIS"\Ubm",pac kH"xP8Il2sK4Ia*(\u hH24PI)K*",74,1I2,2 4H,PHPIL32,1K,4,unIpa cHk(PHPLu=>uc"Kp_/s[I^ -HjPH=PL0d7l3+iK?,v_r kHoPH3[ParLue=anKzg%7= uH)<=y;/_"P),LsortK{ope nH*S,">BHB BL$0.bmPp"} gHrep{s/BN\ BLS/P\t/ ;Hs/.\Bn N BP/\ tH/,unBt N BHil !sH/(.)B[^N BH\h \JPHUb- BqO H]/$ 1JP$H1/B}QO H<0> )JAPH;#UNQ HeaP| &J~~PH';s H[A-R| &~J]|PHq###%jAPHeg ;my$JAPH=eval.'P/ \MP@%J+P__H::$P/ |MPTUJP P___ |MAPZX| \MPWY| |MAP| \MP| |Mw| |Mw/ |M/ |/ '
      If you're curious enough, you might try it. You may also try replacing eval with print, this should print some human-readable code to STDOUT.
