I cosplayed as Waluigi at San Diego Comic-Con this year--you might have seen me in Roger's gallery--hence the avatar. I have a gallery on ImageShack myself.

I even already scored badges to next year's Comic-Con and have already start putting together next year's cosplay. It's much too early to tell you what it will be.
