Pilot Fish is a brand new portfolio theme in the WordPress Theme Directory, created by Daniel Zhao. This theme features a minimalist style with a responsive design and a custom post type for projects / portfolio items.
It also includes a cool parallax scrolling effect that you can only see if you view the live demo.
The portfolio is nicely arranged on a full-width page with mouseover titles linking to each project page.
