The game is being developed by a small team at Techland, a part of them is a group of my friends two of which study with me. Techland is a relatively small Polish video game company.
I believe that one of these said friends was working on that video. At first he was sometimes harassing me about "oh look at this cool model I've made - I will do this and that with it and that'll be pretty cool" and I was like "yeah, right maybe later". That was because there's another major at our uni called "New Media Art" - they do all kinds of computer animations and I've seen more of their works than I'd like because of other friends bombarding me with their projects.
However I was really impressed when I first saw the video. I didn't know that it gets so much fame abroad though.
