Bioshock - Irrational Visit @ Cult of Rapture

2K Games' Cult of Rapture site has a bunch of photos of Irrational's (Boston) offices from a recent visit:

Last week, I went to Irrational Games up in Boston to do some work and meet with the team. The weather was colder, the town quieter, but Irrational’s offices were just as busy as when I was up while they were about to finish Alpha. Now, a few days before Beta, the halls were filled with sounds of screaming children, water lapping, gurgling and gasping voices, and the echo of shooting. It was delightful. I think I’m still having nightmares.
