It's by the same people that did the Trucks** video and the Gorilla playing the drums* video; all three are commercials for Cadbury.
*Have you seen this remix?
**UPDATE: Also a "remix" (more of just a music swap) for Trucks***.
Both of these updated commercials have played officially on TV.
***UPDATE III: There's also apparently one with Final Countdown. Is there anyone who can hear that song now and not think of Arrested Development? There's even a stair-car!
I don't know why, but commercials with music just really do it for me. Like mini music videos. (Also, it helps that the Cadbury commercials are so completely random).
The people that made this have an interesting Myst-like site. What is the mystery word? How far can you jump? Why is Phoenix so very easily amused? The world may never know.
UPDATE II: Saw the following comment on the eyebrows commercial:
