Complex Numbers in Math Class

Yesterday afternoon I did another video trick for my Nature of Math class at Biola University. What's the difference between the real and the imaginary? Can an imaginary person (like a person in a YouTube video) do something outside the confines of a video box?

See the instructions at the end for another version of this question.

Thanks again to Andrew Staver who did most of the work on this video. He's graduating this semester with a degree in Film Production from the Cinema and Media Arts department.
