Not quite the full costume, I'm afraid... I absent-mindedly left the gauntlets and badge behind but I'm flattered you noticed me in there. 
I had so much fun at the event, even though it was a little difficult to communicate, and I'm so glad I met lots of you guys from the forums, IRC and Facebook!
Not difficult to notice you when most people just wear something casual like a pair of jeans and a T-shirt.
At what point did you realise you left the gauntlets and badge, on the way to the airport, halfway through the flight or when you unpacked?
Glad you had a good time over there.
