The blue bar that moves back and forth on some computers that tells you that a website or music selection is downloading or buffering respectively. Named after KITT, David Hasselhoff's (Michael Knight's) Pontiac Trans-Am in "Knight Rider", because of the light above the bumper that moved back and forth.
I'm trying to link to this website, but the KITT bar is taking too long until it stops---I think their server's down.
