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!
I doubt you noticed, but my son (5 years old, spent most of Sunday dancing in front of the Mandala camera) was TOTALLY IN AWE OF YOU. He kept sneaking looks at you, and then whispering to me and Mom "look... she's a super hero!"
I suggested a couple times that he go up and say hi to you, but he was too shy. Oh well - maybe at the 40th Anniversary bash! :-)
