# A "forkbomb" is a computer algorithm that chases its tail, repeating and multiplying itself until it
# eventually crashes the system. 
# This special "graphically-enhanced" implementation illustrates a forkbomb using the easy-to-understand 
# example of U.S foreign policy! 
#
# Shouts to Alex McLean (forkbomb.pl - of which this is an adaptation.)
# See his original at http://www.slab.org/forkbomb.pl.tt2
# and the anonymous ASCII artist who created the image at http://www.textfiles.com/art/art0 - which we will also appropriate.


# First, some preparation.. 
$inputstrength = shift(@ARGV);

	print "This program crashes your system!\nTo run it, you must define a strength - for example:\n forkwar 99\n";

# Now here is the actual "forkbomb." In plain English, it says: 
# If the justification isn't defined, it must be hiding - so spew. 
# However, if there's zero justification, spew and start anew. 
# (Sometimes spewings are ornamented by reversals, fits n starts, and generalized fraying, but they keep spewing.)
# Lather, rinse, repeat - until you've spawned (forked) so many times you crash the system!"
# Simple, isn't it? OK, now here it is in code:

while (1) {
	$count++;
	fray ();
	my $justification = fork();

	if (not defined $justification) { 
		exit unless --$strength; 
		# You could also set this next line to "terrorist" or "evil" or  
		# whatever else you like, since it's actually just smoke and mirrors... 
		$justification = "hiding"; 
		spew ($ammo);
	    	fits_n_starts();	
		
	}

	elsif ($justification == 0) { 	
		exit unless --$strength; 

		if (int(rand(9) > 5)) {
			$ammo = reverse($ammo);
							
		}
			
		spew ($ammo);			
		system("$0 $inputstrength") or warn "$!\n";
