Mostly images, but there are some videos of it in action...

Volpin Props' BioShock costume.

Initial build, and images from initial Dragon*Con appearance.

Recent photo shoot at aquarium. BRILLIANT idea. Results: Phenomenal. More.

His current Ebay auction for the costume. I love some of the text at the bottom, including "Creepy Fiancée shown above is not part of this auction", and "How are we supposed to know what it looks like if you only show the luscious game art? How about some real photos?? Edit: Holy CRAP!"
