Instead of removing time from video (as most timelapses do) I have been working out ways to put more time into each frame. A full minute has been pressed into each frame of video exactly as if you had kept the shutter open in each of the 25 frames per second. By deepening the time in each frame we can experience a compressed duration without sacrificing time itself.
Note that the video has a soundbed of audio samples taken from Metro videos and radio broadcasts. This sound is meant to play quietly in the background. Note also that a much longer cut will be available soon that will feature a proper soundtrack.
Here is a finished video that uses the same technique: vimeo.com/23052224 .
