How do you solve a Rubik's Cube faster?

Here's one method that may impress some of your friends who can't figure it out: get a cube that is already solved. Videotape yourself quickly and frantically unsolving it. Go as long as you like. Then figure out how to play the video backwards. Be sure you don't do anything while taping that will make your trick obvious, like someone casually walking bakwards through the frame, or "pouring" a liquid from a glass back into the bottle. OK, people will catch on, but some may take a little extra time.
