Hah, the Waypoint folks actually asked Delta to get in the picture. We were doing our photoshoot and as he was walking by they said "Hey, let's get Bioshock in there for no reason. Everything's better with bioshock." And then he showed off his actual spinning drill.
I believe the person who won the second Xbox 360 in the masquerade from that is a 405th member named UNSC Anubis 117! Yeah he made that Halo 3 Hunter costume and you can see in the video they award him the Xbox, I tried to see if he posted anything about it but alas I am not sure if he is still on the forums as I could not find his name in the members list.
I actually went searching and found out his new name on the forums is x117anubis but he hasn't posted any new since may of this year. Apparently he finished his costume in time for Comic Con and because of it's originality he won a much deserved prize for all his hard work.
