That screensaver certainly seems out of place considering Jim Carrey.
Do you think it's a psychological experiment? Attempting to make people associate the words in the tunnel with Jim Carrey?

There doesn't seem to be any sort of explanation, and it seems to be an easter egg. Maybe it was thrown in by a rouge programmer?
