Ok guys, I'm afraid I'm going to ask the wrong questions here, but here goes. I'm really digging the feel of this site: Link. I like two things here, and am interested in learning how to do them. One, the .css loader that lets you change the look of the site. Two, the "popup" box that fades in when you roll over the photos. There is a link to the js here. I'm not about ripping this site off, I just want to learn the same techniques so I can apply them to my own design. How tricky is this to do?
