Tilt-Shift Drift Video: Awesome, But I Don’t Get It.

I don’t have a clue of how this is done, but this is apparently a real drift event filmed through a tilt shift camera.  I think it is absolutely awesome, but I don’t have any clue of how it works, which bothers me.  That being said, watch it, enjoy it, and then could somebody please explain to me what the heck tilt-shift photography is?  I read the wikipedia, and I can’t wrap my head around it.  Now all I can think of is the fast talking micro machines guy.
