My first obfu

Need Help??

Be kind, this is my first obfu! This sad little bit of code was something I hacked together for a birthday card for a friend who knows a little Perl.

Yes, I understand that it's extremely simple and can probably be done in less than one line. But hey, give me a break! It took me a little while to come up with something slightly clever, and I'm proud of what I managed. Sorry, no ``JAPH'' this time.

And if you're wondering, this was my (also) sad attempt at an ASCII birthday cake.

$_='
         $
         _
         =
\'})fer(fi)]1[>-_$x
)]0[>-_$(rhc(tnirp;
fer!fi)_$rhc(tnirp{
)_@(hcaerof;)01,121
,79,001,401,611,411
,501,89,23,121,]2,2
11[,79,401(=_@\';ev
al(reverse(split(//
)))';s/\s//g;eval##

Constructive criticism is greatly appreciated.

I golfed it down a little and furthered the obfuscation a bit as well, but kept your basic premise. The golfing removes some of the easy readability of your original code garnered by running the likes of:

        _
        =

And I just noticed that my version seems a bit harder to handily pick apart with sed | Deparse (or variation thereof) - the de-obfuscator needs to do a bit more work.
