After looking at a bunch of examples, now I get it, and it's da bomb. It's like the ski resort video I posted a little while back. Everything that's pictured looks like a miniature, toy set of what it is, even though it's a regular sized scene.
There's also this video from Mardi Gras last year!
It's become my new goal to figure out how to do this and come up with some of my own. I'm no professional photographer, but I do consider myself to be pretty good. Now I just need to figure out the special effects like this.
Any tips/suggestions from the pros would obviously be appreciated.
