I've recently started a project to create and release timelapses under a Creative Commons license. The timelapses I make are available for download from Vimeo and may be used in non-commercial videos. See creativecommons.org/ for more information.
All timelapses I upload are created by me with a Canon 400D, using GBTimelapse to capture the photos and VirtualDub to generate the video. Videos may vary in framerate and resolution.
