I've uploaded all of the images as a 44MB ZIP file.
It includes some pictures of the Guinness World Record attempt.
In this linked shot over at Flickr, I'm in the middle left facing the camera and my wife is the one with the Sims jewel in the background. I went as "Pong" to do my part. My props are on the ground.
I wasn't planning on doing any sort of cosplay at the convention because it just isn't my thing, but the props were easy to make and it helped solidify the record attempt, so it was worth it.
