Lightbox? Gallery? Custom Popup Design

Hello, we love the feel of this site –

We are looking to try to figure out what exactly is it that they are using on the home page, if you click on one of their projects, it pops up a full screen page with a background for that project and information/video… acts like a Lightbox but aren't lightboxes only for Images?

What are they using here and is there a WordPress Plugin that is similar to do this?
