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:

sed s/eval/print/ mpeg.pl | perl | sed s/eval/print/ | perl | perl -MO

@_ = (104, 97, [112, 2], 121, 32, 98, 105, 114, 116, 104, 100, 97, 121
+, 10);
foreach $_ (@_) {
    print chr $_ if not ref $_;
    print chr($$_[0]) x $$_[1] if ref $_;
}

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.
