Very, very cool. One step in particular had me going for a while... Read more for spoilers. 
# This is one big regex which sets
# $_ = ",:_,,},,],,_:){:"},,:,,,,,_,:(,:,,,(:){,,{,:,,,(,:[:){,:(:"}:"
+",:},:,,,("

s;;,:_,,},,],,_:){:"},,:,,,,,_,:(,:,,,(:){,,{,:,,,(,:[:){,:(:"}:"",:},
+:,,,(;;

# This translates individual characters, e.g., all ',' in $_ become 'P
+'.
# $_ = "PQWPPVPPTPPWQRSQXVPPQPPPPPWPQUPQPPPUQRSPPSPQPPPUPQYQRSPQUQXVQX
+XPQVPQPPPU"

y;,:_}][{"();PQWVTYSXUR;;

# This is the step that had me confused.
# It takes each individual character and xors it with 'a'. For example
+:
# a (ASCII 97) xor P (ASCII 80) is ASCII 49 ('1')
# Now $_ = "1061171151160320971101111161041011140321121011141080321040
+97099107101114"

s;(.);a^$1;eg;

# This takes each group of three and prints out their chr(); e.g., 106
+ becomes chr(106) = 'j'
# now $_ = "just another perl hacker"

s!(...)!chr$1!eg;

# Append a newline and print

$_.=$/;
print;
