It would make a wonderful compression algorithm, imagine ;-)

my $md5 = md5($complete_works_of_shakespere); # compress to 128 bits
my $plays = reverse_md5($md5);                # inflate 128 bits into 
+~ 1 M bit.
print $plays;                                 # torture new generation

It is along the lines of loaves and fishes to strech those bits so far....
