Here’s a replica Big Daddy costume shot at the Georgia Aquarium in Atlanta. The designer of the 60lbs costume says,

This costume is a replica of the Bouncer-type Big Daddy from the videogame Bioshock by 2K. This piece was completed in 7 weeks for its debut at DragonCon 2009, where it won 2 awards for “Best Journeyman” and “Best Professional Design.” After initial press after DragonCon, I was contacted by Ken Levine of 2K games who said, “You are the Big Daddy.”

This Bioshock Big Daddy costume is currently up for bid on Ebay.
