A Celebration, if You Can Figure it Out

We were talking about a very cool astrological date on the internal PowerShell mailing list recently. In celebration of this event, Josh Rowe made this brilliant comment. See if you can figure out what it does :)

clear;$00=(0..1250|%{9608}),(0..7645|%{9617})|%{$_};(-10..29)|
%{$OO='';$O0=$_;-10..64|%{$0O=$_;$OO+=[char]($00[$0O*$0O-48*$0O+

I suppose that’s not really fair. Here it is in all of its syntax-highlighted glory:

clear;$00=(0..1250|%{9608}),(0..7645|%{9617})|%{$_};(-10..29)|
%{$OO='';$O0=$_;-10..64|%{$0O=$_;$OO+=[char]($00[$0O*$0O-48*$0O+
1720+4*$O0*$O0-96*$O0],@($00[$0O*$0O-52*$0O+1644+4*$O0*$O0-88*
$O0],9617,9617)[(0,1)[($0O-lt28)]+($O0-gt12)])[(0,1)[$0O-gt24]*
($O0-lt14)]};$OO};0..573892165|%{$OO[email protected]((($OO+0)*4*$_*$_/(4*$_*
