Nobody's won yet.

I'm going to bed without declaring a winner.  I've had some great entries, but I'm not convinced I've got a real sample yet.  I may keep this particular quiz going for a little while as I dream up the next nasty code for you to crack.  I didn't expect this to be nearly as much fun as it has been so far.  In fact, I was so jazzed by that chase through virtual Dublin that I booked a visit to the real place in June for Bloomsday.  Too bad about those internet travel brokers and thank dog for no pre-set spending limit.  I'd better not set any codes in Antarctica.  It's also pretty high on my wish list.
