I really like how responsive and interactive this site is. There are a lot of unique features on this website that I haven't seen before. For example, the hover state on the nav bar links is like 2 corners of a frame. The site is also very touch screen friendly. On the homepage, you have to swipe right to see the work in the work section. On the nerds page, you spin the dial around the employee to see different employees. This definitely seems like the site was designed mobile first.
