Back in college we borrowed a Blackmagic Cinema Camera to film a big homework project, and after finishing I asked a friend to take a video of me in reverse. Then take a couple of closer stills for the inwards transition.
Done in After Effects, I used some very simple effects and overlays for the colours and a Kaleido script for the trip. Then the tube-thing was done with Particular then turned to a Ripple Coordinates texture for a 3D cylinder.
