Playing around with C4D and AE.
Made this with several techniques I learned after following some tutorials from http//:greyscalegorilla.com
I used camera mapping for the tunnel textures using this Florian Schütz's photograph as the source: flickr.com/photos/effpunkt/101127281/
Text and spheres' physics were calculated using the mograph module and modynamics tags, I used the wind deformer and a low gravity in order to keep the elements floating around for longer. No keyframes were used at all, not even for the camera movement, since I used CS tools' DocuCam .
Post production was made in After Effects with Frischluft Lenscare plugin for the Depth of Field camera blur simulation, Knoll Light Factory for the lens flares and Red Giant's Magic Bullet Looks for color correction with a tweaked preset from Nick Campbell's Vintage Film for Looks.
EDIT: Ps. I just noticed a little glitch at 0:02, it appeared after I uploaded it, got no idea why.
