Big Screen Fade In / Fade Out

A while back I saw this website that when I clicked a picture, the whole screen dimmed, and in the middle of the screen, what I clicked was enlarged and bright.

I never had the time to figure out what this was, recently, I stumbled across ThickBox which does just what I'm looking for - It's in DHTML/JavaScript. Take a look:

Thickbox - One box to rule them all.
